(1) General purpose plastics

General-purpose plastics generally refer to plastics with large customized Plastic Cup output, wide use, relatively low performance, and low price, such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, phenolic plastics, amino plastics, etc. 60% of the total output.


(2) Engineering plastics

Engineering plastics refer to plastics that can be used as structural materials. There is no obvious boundary with general plastics. Engineering plastics have relatively good strength, impact resistance, heat resistance, hardness and aging resistance, and can replace some metal materials. Used as engineering materials, such as nylon, polycarbonate, polyoxymethylene, ABS, etc.


(3) Special plastics

Refers to those plastics that have special functions and are suitable for certain special occasions. They mainly include medical plastics, photosensitive plastics, magnetically conductive plastics, superconducting plastics, radiation-resistant plastics, and high-temperature plastics. Its main component is resin, some are specially synthesized resin, and some are made of the above-mentioned general plastics and engineering plastics resins to obtain special properties after special treatment or modification. This type of plastic has a small output, excellent performance and high price.
