Three hot spots in the new material industry

1

01

One of the three hot spots: aramid, PI and PA

⏬ Aramid - a key strategic material

Aramid has high-end downstream applications and is a key strategic material.

Aramid products are characterized by high thresholds, few domestic companies, obvious localization substitution trends, and an obvious upward trend in the industry.

The threshold for aramid products is mainly technology and customer access. To enter the market, safety certification is required, which requires several years of successful cases. Downstream application fields have high safety requirements.

At present, the global para-aramid is in a near-balanced state, and 80% of domestic para-aramid relies on imports. From a global perspective, with the increase in application fields, the demand for para-aramid fiber will gradually increase. It is expected that the global demand for para-aramid fiber will reach about 150,000 tons in the next five years. Calculated based on an annual growth rate of 10%, China's demand for para-aramid fiber will reach 13,000 tons in 2020, and the demand for para-aramid fiber will reach 25,000 tons in 2025.

The global meta-aramid fiber industry is mainly occupied by companies such as DuPont of the United States, Taihe New Materials, and Teijin of Japan. Among them, DuPont ranks first with 67% of its production capacity, and Teijin accounts for 7%.

⏬ Polyimide - "Problem Solving Expert"

Polyimide is one of the organic polymer materials with the best comprehensive performance. It has a high temperature resistance of over 400°C and a long-term use temperature range of -200~300°C. Some of them have no obvious melting point and have high insulation properties. The dielectric constant at 103 Hz is 4.0, and the dielectric loss is only 0.004~0.007, belonging to F to H.

PI film

PI film is the earliest and most mature product among the PI series products. It is the best choice for insulating films. The wave of localization of high-end products is approaching.

Domestic self-sufficiency has been achieved for PI films below electronic grade, while the PI film market for electronic grade and above is still mainly divided among overseas companies.

With the gradual implementation of domestic chemical imine production lines, domestic manufacturers will participate in sharing the nearly 10 billion high-end market. In the future, as the FCCL market maintains a high growth rate and the rapid popularization of OLEDs increases the demand for flexible substrates, the high-end electronic grade PI film market will be in a period of rapid expansion.

PI fiber

has taken root in the military market and accelerated the development of the civilian market. PI fiber has excellent heat resistance and mechanical properties. It is a core accessory material in important fields such as aerospace and military aircraft. Its application in the military market is irreplaceable.

In the commercial field, the application of PI fiber in environmentally friendly filter materials, fireproof materials and other applications is currently in the gestation period, and is expected to add new vitality to PI fiber in the future.

PI/PMI foam

Benefit from the upsurge of warship construction and welcome the "blue ocean" era. The most important application of PI foam at present is heat insulation and noise reduction materials for ships. Our country's navy is currently in the third wave of shipbuilding. As the preferred heat insulation and noise reduction material for new warships, PI foam is expected to rapidly increase demand in the future. In addition, PMI foam, as the most excellent structural foam core material, is widely used in wind turbine blades, helicopter blades, aerospace and other fields. It has a clear replacement trend for PET foam and has a broad market space.

PI-based composite materials

Lightweighting is a major trend, focusing on the high-end market. Fiber-reinforced composite materials are a new generation of lightweight materials after magnesium-aluminum alloys. Composite materials with polyimide as the resin base have excellent high temperature resistance and tensile properties and are widely used. As the carbon fiber industry gradually matures, the demand for carbon fiber reinforced composite materials has increased significantly. As one of the most excellent composite material combinations, the combination of polyimide + carbon fiber has obvious advantages in seizing the high-end market.

PSPI (photosensitive polyimide)

develops its efforts in the dual fields of photoresist and electronic packaging, and enjoys the dividends of high-end electronic products. Photosensitive polyimide mainly has two major applications: photoresist and electronic packaging. Compared with traditional photoresists, PSPI photoresist does not need to be coated with photoblockers, which can greatly reduce the processing steps. At the same time, PSPI is also an important electronic packaging glue.

Photosensitive polyimide can be used as a packaging material for: buffer coatings, passivation layers, α-ray shielding materials, interlayer insulation materials, chip packaging materials, etc. It is also widely used in the microelectronics industry, including integrated circuits and multiple In the packaging of chip packages, etc.

⏬ Nylon

High temperature resistant nylon

High temperature nylon has relatively high technical barriers to . The industry has not been developed on a large scale, and there is a huge gap in market demand for . The research on high-temperature resistant nylon in my country is relatively late, and the development of new varieties is mainly based on PA6T modification, supplemented by the synthesis of new nylons.

As a high-performance engineering material, the market for high-temperature nylon continues to expand. It is expected that China's demand for high-temperature nylon will grow at a rate of 15% to 25% in the next few years.

The potential demand for high temperature resistant nylon accounts for 20-30% of nylon, and the demand for nylon in the Chinese market is expected to reach 10,000 tons within five years .

Nylon elastomer

Nylon elastomer is a polyester/polyether-polyamide block copolymer. The most common one is polyether block amide (PEBA). Its more prominent properties are high resilience, light weight and low temperature resistance. Impact performance. The energy return of

nylon elastomer can reach 85%, which is about 15% higher than Boost cushioning technology, and has better shock-absorbing and buffering effects. Compared with TPU, it is lighter in weight.

The synthesis technology threshold for nylon elastomers is relatively high , and most of them are in the hands of large foreign manufacturers such as Arkema of France, Evonik of Germany, and Ube Industries of Japan.

The market demand for nylon elastomers has huge potential . In addition to the demand for base materials of 44 billion pairs of shoes per year, there are also alternatives to polyurethane soft foam and plastic track materials.

In 2017, global sales of liquid crystal polymer films and laminates were approximately 9,050 tons, with a compound annual growth rate of 6.7%.

express packaging film will show the development trend of reduction, greening and recycling.

backlight module optical film will tend to develop with high brightness, thinness, lightweight and high color gamut.

Optical Polyester film Industry

Functional polyester raw material preparation technology is one of the core technologies of film-making enterprises. Nano-micron addition modification involves slip uniformity, crystallization uniformity and electrostatic voltage film properties, etc. It is the technical bottleneck that hinders the development of the industry.

The domestic optical polyester film industry is still in its infancy, and most of it focuses on the stretching and molding processing of the film, lacking systematic research on optical polyester film technology.

It is difficult to compete with international giants in terms of optical polyester film materials (special slices and masterbatch), formula design, equipment and process control. These have restricted the development of my country's new display and other industries; third, the industry's overall technological innovation is lacking Collaboration and linkage.

BOPA Film industry

BOPA film is mainly used in packaging fields such as food, daily chemicals, medicine, electronics, construction, machinery, etc. Food packaging accounts for 70%-80% of the share, and is mainly used for high-temperature cooking, freezing, and snack foods. .

predicts that in the next few years, China's flexible packaging and BOPA film markets will continue to show growth, and overseas markets will become another new growth point.

BOPET film industry

BOPET film Because of its excellent physical and chemical properties and environmental protection performance, BOPET is known as one of the new materials with the most development potential in the 21st century.

my country’s BOPET polyester film demand accounts for 33% of the global demand.

downstream application industries are mainly in the production fields of packaging materials, electronic information, electrical insulation, protective cards, imaging films, hot stamping foils, solar energy applications, optics, aviation, construction, agriculture and other production fields.

At present, the largest application field of polyester films produced by domestic manufacturers is the packaging industry, such as food and beverage packaging, pharmaceutical packaging, and some special functional polyester films are used in high-end fields such as electronic components and electrical insulation.

BOPP film industry

BOPP film is known as the "Queen of Packaging". my country's apparent consumption of BOPP film was 2.51 million tons in 2013 and reached 3.3 million tons in 2017, an increase of 32% in five years.

With the continuous improvement of my country's consumption level and the rapid development of post-processing color printing composite, lamination, aluminum plating, coating and other industries, the demand for BOPP film has great market potential.

BOPE film industry

BOPE film industry will become a hot spot in the film industry. It has the following advantages:

◼ high transparency, high gloss, and few crystal points;

◼ high stiffness and high tensile strength ;

◼High puncture resistance;

◼Excellent low-temperature impact strength and pinhole resistance, abrasion resistance, excellent low-temperature flexibility;

◼Long wetting tension retention time, good printing performance, and accurate overprinting.

◼Using half-thickness BOPE to replace blown materials or cast CPE films and dry lamination such as BOPA or BOPET can achieve the same heat sealing strength and close stiffness;

◼And using half-thickness BOPE to replace blown materials or cast CPE films Dry lamination of extended CPE film and BOPA for frozen packaging can greatly reduce the bag breakage rate.

02

Two of the four major materials: 3D printing materials

Currently commonly used 3D printing polymer materials include polyamide, polyester, polycarbonate, polyethylene, polypropylene and ABS. Although the most common market materials for 3D printing are ABS and PLA, nylon is actually the most widely used material. predicts that by 2022, nylon will occupy 30% of the 3D printing material market.

The main factors that affect the application of materials in 3D printing are: high printing temperature and poor material fluidity, which lead to the presence of volatile components in the working environment. The printing nozzle is easily clogged, affecting the precision of the product; ordinary materials have low strength and their adaptability is too narrow. , the material needs to be enhanced; the cooling uniformity is poor, the shaping is slow, and it is easy to cause the product to shrink and deform; it lacks functional and intelligent applications.

Global 3D printing market (billion US dollars)

Application field analysis

Industrial field Large-scale industrial applications in the future are expected to usher in explosive growth in the global 3D printing market.

• In the industrial field, 3D printing has formed a complete industrial chain after 30 years of development.

• At present, 3D printing technology has been applied to some extent in the fields of military, aerospace, medical, automobile, machinery and equipment manufacturing and consumption.

• 3D printing is used in construction, building load-bearing parts, auto parts, and industrial parts. A group of leading companies have gathered in every link of the industrial chain.

The development direction of 3D printing materials in my country

• With the development of 3D printing technology, the performance of traditional materials has been greatly improved. The material's powerful rapid melt deposition and low-temperature bonding properties will be widely used in the field of 3D printing manufacturing. In addition to the materials themselves that can be 3D printed, 3D printing on glass, ceramics, inorganic powders, metals, etc. all depends on the adhesion of the materials.

• By modifying the strength of the material, it can be used to directly replace metal for various complex components, which is both cheap and lightweight. It can even replace glass, ceramics and other products, making the material widely used in 3D manufacturing.

• materials can avoid the shortcomings of low strength and develop towards composites and functionalization, especially the realization of multi-material composites to give materials specific functions. Use 3D printing technology to manufacture complex smart materials, optoelectronic polymer materials, photothermal polymer materials, photovoltaic polymer materials, energy storage polymer materials and other new materials.

3D printing can advance China’s manufacturing industry by 5-10 years because it does not require molds and rapid repair of parts. 3D printing can be called a revolution in the industry.

03

The third of the four major materials: degradable materials

Biodegradable materials segmented application fields (10,000 tons)

• It is expected that by 2020, my country's biodegradable material output will reach 2.5 million tons. The "13th Five-Year Plan", international carbon cap laws, and the improvement of biodegradable material performance and price reduction will bring unprecedented development opportunities to China's biodegradable materials industry.

• Completely biodegradable materials mainly include PLA, PHA, PBS/PBSA, PCL, PVA, PPE/PPC/PPB and a small amount of PSM, etc.Biodestructive materials mainly refer to materials modified by biodegradable resins on traditional polyolefins, and most of PSM fall into this category.

• The development of biodegradable materials is increasingly in line with society's environmental protection concepts. Currently, there are dozens of varieties of biodegradable materials developed around the world, but only PSM, PLA, PBS/PBSA, PHA, PCL, etc. have been produced in batches and industrialized .

2015-2020 Global demand for three major biodegradable materials is forecast

04

The fourth of the four major materials: new elastomer

propylene-based elastomer

propylene-based elastomer is produced using a combination of metallocene catalytic technology and solution polymerization process, which is unique Propylene-ethylene semi-crystalline copolymer has unique high elasticity, flexibility and low-temperature impact resistance, especially excellent compatibility with PP.

Currently, only three companies in the world have commercialized propylene-based elastomers. The brands are Dow's Versify, ExxonMobil's Vistamaxx and Mitsui's Tafmer.

Propylene-based elastomer advantages:

◼Propylene-based elastomers have the characteristics of good feel, high filling, and good anti-slip properties, such as the foaming advantages of ExxonMobil vistamaxx;

◼VM foam products have good feel and good density. , and has a gluey feel;

◼ has high filling, and the filling amount can reach 100phr, while the filling amount of EVA is generally 30phr, which has great advantages in reducing costs and making certain functional materials, such as making flame retardant materials. Performance depends on filling;

◼ can be 100% recycled, and the foamed product will not have poor distribution of pores on the product surface. However, if too much recycled material is added to EVA foam (generally the amount is 30phr), it will There will be a phenomenon of poor density distribution;

◼Using VM to do some relatively low hardness foaming processes is much easier to operate than EVA. If the hardness of EVA reaches 10°C, it is quite difficult, and SEBS is generally added to increase the softness, but VM is easy to do;

◼The improvement of impact strength brings opportunities for thinning, which can reduce the use of materials and lower the cost. Cost;

◼ Propylene-based elastomers have a lower melting temperature, which reduces processing temperatures, and their higher flow rates increase processing speeds. This reduces energy consumption and increases processing efficiency. Its flexibility helps increase draw ratios and reduce flow marks, resulting in better product quality and lower scrap rates. Because this elastomer shrinks less than polypropylene, the production process is easier to control and the die-cutting is more accurate, thereby improving the fit of the cup and lid and helping to reduce scrap rates.

Application of propylene-based elastomer:

◼ Random copolymerized propylene (RCP) is widely used in the field of food preservation boxes, but there is a common problem of insufficient low-temperature impact resistance. Propylene-based elastomers are used to modify polypropylene and can improve the toughness of polypropylene. As a toughening agent in RCP, it can improve the toughness while maintaining the transparency of RCP, helping to reduce the stress whitening of the hinge structure;

◼Blending propylene-based elastomer with polypropylene (PP) can achieve better It has a balance of impact resistance, transparency and stiffness, and can also improve processing efficiency;

◼ can be used in non-woven fabrics, elastic films, polymer modification, etc. Among them, polymer modification has excellent performance. Specific application cases include washing machines Seat trays, food container lids, humidifier water tanks, plastic stationery, sports bottles, slippers, etc. Performance and characteristics of

vinyl elastomer

vinyl elastomer:

• The polyethylene chain crystallization region (resin phase) acts as a physical cross-linking point and has typical plastic properties. A certain amount of α-olefin (1-butanol) is added After ethylene, 1-hexene, 1-octene, etc.), the crystalline area of ​​the polyethylene chain is weakened, forming an amorphous area (rubber phase) showing rubber elasticity, making the product have the properties of an elastomer; POE has the properties of a plastic The dual characteristics of plastic and rubber have excellent comprehensive performance, so POE can be regarded as a bridge product between plastic and rubber.

• Compared with EPDM, POE elastomer has the advantages of excellent weld line strength, good dispersion, high impact strength with equal addition, and outstanding molding ability; compared with SBR, it has good weather resistance, high transparency, and low price , has the advantages of low density; compared with EVA, EMA and EEA, it has the advantages of low density, high transparency, good toughness and good flexibility; compared with soft PVC, it has the advantages of no need for special equipment, low corrosion to equipment, It has the characteristics of good thermoforming, good plasticity, low density, good low temperature brittleness and good economy.

• POE elastomer, as a plastic toughening agent, can not only toughen and modify polyolefin plastics that are compatible with it, but can also be initiated by peroxide and effectively undergo grafting reactions with monomers such as maleic anhydride and glycidyl acrylate. , the obtained graft is widely used to toughen engineering plastics such as nylon and polyester.

• Polyolefin elastomer POE has no unsaturated double bonds in its molecular structure and has a very narrow molecular weight distribution and short branched structure (short chain branches are evenly distributed), so it has excellent physical properties such as high elasticity, high strength, and high elongation. Mechanical properties and excellent low temperature resistance.

• The narrow molecular weight distribution prevents the material from deflecting during injection and extrusion processing, so POE materials have excellent processing properties. Due to the saturated structure of the POE macromolecular chain, the molecular structure contains relatively few tertiary carbon atoms, so it has excellent heat aging resistance and ultraviolet resistance. In addition, it effectively controls the introduction of long branches into the linear short-chain branched structure of the polymer, which improves the transparency of the material and effectively improves the processing rheology of the polymer.

Applications of vinyl elastomers:

◼POE can threaten materials such as rubber, flexible PVC, EPDM, EPR, EMA, EVA, TPV, SBC and LDPE;

◼ is used in different products, such as automobile baffles, flexible conduits, Conveyor belts, printing rollers, sports shoes, wires and cables, automotive parts, durable goods, extruded parts, molded parts, sealing materials, pipe fittings and fabric coatings, etc.;

◼ can also be used as a low-temperature impact modifier to improve the properties of PP It has low-temperature impact resistance and can be used as a thermoplastic elastomer in the automotive field.
