The material of the PC protective case is polycarbonate.
Polycarbonate is a strong thermoplastic resin that gets its name from the CO3 group within it. It can be synthesized from bisphenol A and carbon oxychloride (COCl2). The more commonly used method is the melt ester exchange method (bisphenol A and diphenyl carbonate are synthesized by ester exchange and polycondensation reactions).
According to the different structure of the alcohol, polycarbonate can be divided into two categories of aliphatic and aromatic. Aliphatic polycarbonate. Such as polyethylene carbonate, polytrimethylene carbonate and its **** polymer, low melting point and glass transition temperature, poor strength, can not be used as a structural material; but the use of its biocompatibility and biodegradable properties, can be in the slow-release carriers for drugs, surgical sutures, bone support materials and so on to obtain applications.
