ABS and PP materials are both common plastic materials. To compare which of the two is better, we need to first understand the characteristics of the two.
1, ABS material
ABS is an acrylonitrile-butadiene-styrene copolymer, a polymer structural material with high strength, good toughness, and easy to process and mold. It is also called ABS resin .
ABS engineering plastics have an ivory appearance and can be made into colorful particles, with a relative density of around 1.05, low water absorption, good bonding with other materials, easy to coat, plating and printing on the surface, and are flammable polymers, the flame is yellow, black smoke, and special cinnamon smell.
ABS will not be affected by various acids such as water, inorganic salts, alkalis, etc., have relatively good mechanical properties, good impact strength, and can be used normally at extremely low temperatures. However, the weather resistance is relatively poor, and it is easy to degrade under ultraviolet rays. After half a year of outdoor use, the impact intensity itself will drop by half.
has greater creep resistance than PSF and PC, but is smaller than PA and POM. ABS also has good electrical insulation and can be used in most environments. The bending and compression strength of ABS are relatively poor in plastics, and the mechanical properties of ABS are greatly affected by temperature. Its thermal deformation temperature is 93-118 degrees Celsius, and its active temperature range is within minus 40 to 100 degrees Celsius.
ABS is mostly used in automobiles, electronics and electrical appliances, and is also common in building materials and DIY fields. ABS's applications in the automotive field include automotive dashboards, body outer panels, interior decorative panels, door locks, bumper , ventilation duct and other components.
In terms of electronic and electrical appliances, it includes refrigerators, TVs, washing machines, air conditioners, computers, copiers and other products. Building materials include ABS pipes, ABS sanitary ware, ABS decorative panels, etc.
2, PP material
PP is polypropylene material. It is non-toxic, odorless and odorless. It is a white high-crystalline polymer with a density of only 0.9-0.91g/m³. It is one of the lightest plastics.
PP is very stable in water, and the water absorption rate is only 0.1%. It has excellent comprehensive performance. PP products are light in quality, good toughness and chemical resistance, with melting point above 220, thermal deformation temperature is around 121 degrees, and are non-toxic in the range of minus 30 to 140 degrees Celsius.
PP is also the only material that can be put into a microwave oven. It can be used repeatedly after cleaning. Because of these characteristics of PP, it is often used in basins, buckets, furniture products, films, woven bags, car bumpers, bottle caps, etc. PP is non-toxic, environmentally friendly and recyclable.
From the above information, we can know that ABS has good comprehensive performance and its application scope is in electrical appliances, automobiles, aircraft and other industries. The PP material has good fluidity, low hygroscopicity, and a higher thermal deformation temperature than ABS. Its application scenarios are mostly daily necessities and has a wide range of uses. The performance advantages of the two materials
ABS and PP are different, and their application fields are also different. When using these two materials, you need to choose according to the environment. You cannot simply compare which one is better.
