Plastics can also be divided into general plastics, engineering plastics, special plastics according to the scope of application
Common plastics are: PP, PVC, PE, PS, etc .;
Common engineering plastics are: ABS, PC, PMMA, POM, PA6, PA66, PET, PBT, SAN, etc .;
Common types of special plastics are: PPS, PEI, etc .;
Thermal properties: glass transition temperature (Tg> and melting point (Tm> high, heat distortion temperature (HDT> high, long-term use temperature high (UL-746B>, wide use temperature range, small thermal expansion coefficient.
Mechanical properties: high strength, high mechanical modulus, low creep, wear resistance, fatigue resistance.
Chemical resistance, excellent electrical resistance, flame resistance, weather resistance, good dimensional stability.
