PC plastic materials are known as polycarbonates. The English name of polycarbonate is Polycarbonate, abbreviated as PC. It is a generic name for a type of polymer compound containing a carbonate structure in a molecular chain and a variety of materials based on it. According to the different ester groups in the molecular structure, they can be divided into aliphatic, alicyclic, aromatic and fat, aromatic and other major categories. And bisphenol A type polycarbonate is the most important, the molecular weight is usually 3-10 million. Unless otherwise stated, commonly referred to as polycarbonate refers to bisphenol A polycarbonates and modified varieties thereof. Because of its excellent mechanical properties, it is commonly known as bulletproof rubber.
PC plastic raw material features
1, a high strength and elasticity coefficient, high impact strength, wide temperature range.
2, a high degree of transparency and free dyeing.
3, H.D.T. High.
4, excellent electrical characteristics.
5, tasteless and odorless harmless to the human body in line with health and safety.
6, low molding shrinkage, good dimensional stability.
Application of PC plastic materials
Electronic appliances: CDs, switches, home appliances, signal tubes, and telephones.
Automobiles: bumpers, distribution boards, safety glass.
Industrial parts: camera body, implement shell, helmet, goggles, safety lens.
Heat resistance, impact resistance, flame retardant, good mechanical properties in normal use temperature. Compared with polymethyl methacrylate, the performance of polycarbonate is excellent in impact resistance, high refractive index, good processing performance, and UL94V-0 grade flame retardant without additives. However, polymethyl methacrylate has a relatively low price relative to polycarbonate and can produce large devices by bulk polymerization. With the ever-increasing scale of polycarbonate production, the price difference between polycarbonate and polymethyl methacrylate is shrinking. Polycarbonate has poor abrasion resistance. Some polycarbonate devices for wear-resilient applications require special treatment of the surface.
