What are the common plastic materials

Plastic raw materials can also be divided into general plastics, engineering plastics and special plastics according to the scope of application;

Common general plastics include: PP, PVC, PE, PS, etc;

Common engineering plastics include ABS, PC, PMMA, POM, PA6, PA66, pet, PBT, San, etc;

Common special plastics include PPS, Pei, etc;

Engineering plastic particles are often modified by some general plastics; Such as changing the molecular structure of some inner parts and adding other components and auxiliary materials such as glass fiber;

Engineering plastics are industrial plastics used as industrial parts or shell materials. They are excellent in strength, impact resistance, heat resistance, hardness and aging resistance.

The Japanese industry defines it as "a high-performance plastic that can be used for construction and mechanical parts, with heat resistance above 100 ℃, and is mainly used in industry". -- Motorcycle Accessories Mold Manufacturers

Its performance includes:

a. Thermal properties: high glass transfer temperature (TG) and melting point (TM), high thermal deformation temperature (HDT), high long-term use temperature (ul-746b), large use temperature range and small thermal expansion coefficient.

b. Mechanical properties: high strength, high mechanical modulus, low creep, wear resistance and fatigue resistance.

c. Other: chemical resistance, excellent electrical resistance, fire resistance, weather resistance, and good dimensional stability.
