Plastic raw materials are a relatively large category. According to the purpose or characteristics of plastic raw materials, they are often divided into four categories: general plastic raw materials, thermoplastic elastomer raw materials, engineering plastic raw materials, and thermosetting plastic raw materials.
General plastics, such as PE/PP/PVC/PS, engineering plastics ABS/POM/PC, and many other special plastics, such as high temperature, high humidity and corrosion resistance, and other plastics modified for special purposes. The main raw materials of plastics are synthetic resins. In the early days, Coal tar products and calcium carbide Calcium carbide were mainly used, such as ethylene, propylene, etc. First, the appropriate macromolecular components in oil and natural gas were extracted and first cracked into monomers, Then it polymerizes into polymers and becomes plastic.
