PC Engineering Plastic PC with excellent performance of release agent

Description :

　　Polycarbonate is a tough thermoplastic resin, named after its internal CO3 group. It can be synthesized from bisphenol A and carbon oxychloride (COCl2). The commonly used method nowadays is the melt ester exchange method (synthesis of bisphenol A and diphenyl carbonate through ester exchange and condensation reactions).

　　Density: 1.18-1.22 g/cm ^ 3 Linear expansion rate: 3.8 × 10 ^ -5 cm/° C Thermal deformation temperature Answer: 135 ° C Low temperature -45 ° C

　　The three major application areas of PC are glass assembly industry, automotive industry, and electronics and electrical industry, followed by industrial machinery parts, optical discs, packaging, computer and other office equipment, medical and health care, film, leisure and protective equipment, etc. PC can be used as door and window glass, and PC laminated panels are widely used for protective windows in banks, detention centers, and public places, as well as for aircraft cabin covers, lighting equipment, industrial safety barriers, and glass. PC boards can be used for various signs, such as fuel pump dials, car instrument panels, warehouse and outdoor commercial signs, dot type sliding indicators. PC resin is used for car photography systems, instrument panel systems, and interior decoration systems, as front lampshades, reinforced car front and rear bumpers, reflective mirror frames, door frame covers, operating rod sleeves, blocking plates. PC is used as junction boxes, sockets, plugs and sleeves, gaskets, TV conversion devices, communication cable connectors under telephone line brackets, switch boxes, telephone exchanges, distribution panel components, relay housings. PC can be used as low load parts for household appliance motors, vacuum cleaners, hair washers, coffee makers, toasters, power tool handles, various gears, worm gears, shaft sleeves, etc. Guidelines and refrigerator shelves.

　　PC plastic, scientific name polycarbonate, is a high molecular polymer containing carbonate ester groups in its molecular chain. According to the structure of the ester groups, it can be divided into various types such as aliphatic, aromatic, and aliphatic aromatic. Due to the low mechanical properties of aliphatic and aliphatic aromatic polycarbonate, their application in engineering plastics is limited. Currently, only aromatic polycarbonate has achieved industrial production. Due to the unique structural properties of polycarbonate, it has become a rapidly growing general-purpose engineering plastic among the five major engineering plastics.

　　PC engineering plastics are polycarbonate resins polymerized by ester exchange (melt method) reaction of bisphenol A in dihydroxy compounds and diphenyl carbonate in carbonate compounds.
