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

04 Four of the four major materials: New elastomer

Propylene-based elastomer

Propylene-based elastomer is produced using a combination of metallocene catalysis 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.

Advantages of propylene-based elastomers:

◼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. Its performance relies on filling;
◼ can be 100% recycled, and the foamed product will not have poor distribution of pores on the product surface, while EVA foamed will not work if too much recycled material is added (generally the amount is 30phr). 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 it is generally necessary to add SEBS to increase the softness, but VM is easy to do;

◼The improvement of impact strength brings opportunities for thinning, which can reduce material use and reduce costs. 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 improve draw ratios and reduce flow marks, resulting in better product quality and lower scrap rates. Because this elastomer has a lower shrinkage rate 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 the scrap rate.

Applications of propylene-based elastomers:

◼ 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.

Vinyl elastomer

Performance and characteristics of vinyl elastomer:

  • The polyethylene chain crystallization zone (resin phase) acts as a physical cross-linking point and has typical plastic properties. Add a certain amount of Îą-olefin (1-butan 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 also can be initiated by peroxide , effectively contacting monomers such as maleic anhydride and glycidyl acrylate. Branch reaction, the resulting graft is widely used to toughen nylon, polyester and other engineering plastics.
  • 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 of
  • 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;

◼Apply to different products, such as car baffles, flexible ducts, 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 in the automotive field as thermoplastic elastomer.

have tailor-made material properties and responses. Using structured materials for lightweighting can improve energy efficiency, payload capacity and life cycle performance as well as quality of life.

Future research directions include developing robust methods for decoupling and independent optimization properties of , creating structured multi-material systems, etc.

We do not want new materials to be understood at the chemical level, but should be used to maximize their physical properties.

02 Five Focuses Two: Energy Materials Research and development directions include:

Continue to develop materials that convert solar energy into electrical energy such as amorphous silicon, organic photovoltaics, perovskite materials, develop new luminescent materials, and develop low-power electronic devices , developing new materials for resistive switching to advance neuromorphic computing.

Researchers at Okayama University in Japan recently developed a new solar cell made of iron oxide compounds. The light absorption rate of this solar cell is more than 100 times that of previous solar cells made of silicone. Research directions of

catalytic materials: Theoretical prediction of

improved catalytic materials, synthesis of inorganic core/shell nanoparticles with high catalytic performance, scalable synthesis scheme of efficient catalysts suitable for industrial production and application, cocatalyst in the active site in catalytic reactions Selective deposition on the field, study of two-dimensional material catalysts.

03 Five Focus Three: Extreme Environment Materials

Extreme environment materials refer to high-performance materials that can operate satisfactorily in various extreme operating environments.

Research directions include:

◼Develop the next generation of extreme environment materials based on scientific design, such as using the understanding of temperature-related nanoscale deformation mechanisms in materials to improve the design of alloys, and using the scientific understanding of corrosion mechanisms to design new Corrosion-resistant materials;

◼ Understand the performance limits and basic degradation mechanisms of materials under extreme conditions.

04 Five Focus Four: Materials for Carbon Capture and Storage

◼Materials for carbon capture and storage include: carbon capture based on solvents, adsorbents and membrane materials, new carbon capture materials such as metal organic frameworks, electrochemistry capture, carbon sequestration through geological materials.

◼Material issues for clean water involve scientific phenomena of membranes, adsorbents, catalysts and interface materials in underground geological formations, requiring the development of new materials, new characterization methods and new interface chemicals.

◼Material research in renewable energy storage is based on:

Develop multivalent ion conductors and new battery materials to increase the energy density of lithium-ion batteries, and develop new materials for high energy density hydrogen storage to achieve water splitting/fuel cell energy system.
