Plastics are divided into general plastics, engineering plastics, and special plastics according to their use characteristics; general plastics are used in large quantities and have ordinary strength; engineering plastics: slightly smaller in quantity, but with higher mechanical strength;
General plastics: PP, PE, PS, PVC, ABS
There are five major engineering plastics: PA, PC, PBT/PET, POM, MPPO
Special engineering plastics in engineering plastics: PPS, PEEK, LCP, polysulfone, fluoroplastics, etc.;
According to the physical and chemical properties, it can be divided into thermoplastic plastics and thermosetting plastics. According to the processing methods, it can be divided into molding, laminating, injection molding, extrusion, blow molding, pouring plastics, reaction injection clinker, etc.
