Application analysis of PC transparent plastic raw materials in the industry
Transparent plastic raw materials form alloys or blends with different polymers to improve material properties. Specifically, there are pc/abs alloy, pc/asa plastic raw materials, pc/pbt alloy, pc/pet alloy, pc/pet/ elastomer blend, pc/mbs blend, pc/ptfe alloy, pc/pa alloy, etc., which have the performance advantages of the two materials and reduce the cost. For example, in pc/abs alloy, PC mainly contributes to high heat resistance, good toughness and impact strength, high strength and flame retardancy, while ABS plastic raw materials can improve formability, apparent quality and reduce density.
The three major application fields of plastic raw materials are glass assembly industry, automobile industry, electronics and electrical industry, followed by industrial machinery parts, optical discs, packaging, computers and other office equipment, films, leisure and protective equipment.
Polycarbonate is a thermoplastic resin with [o-r-o-co] - links in the main chain of the molecule. According to the different ester groups in the molecular structure, it can be divided into aliphatic, alicyclic and aliphatic aromatic types. Among them, aromatic polycarbonate is of practical value, and bisphenol a polycarbonate is important. The molecular weight is usually 30000-100000. Polycarbonate, English name polycarbonate, referred to as PC.
Plastic raw material is an amorphous, odorless, highly transparent colorless or yellowish thermoplastic engineering plastic raw material, which has excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, bending strength and compression strength; Small creep and stable size; It has good heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide temperature range, and can be used for a long time at -60~120 ℃; There is no obvious melting point, and it is molten at 220-230 ℃
