Product Series
PC
Overview
Polycarbonate, English name Polycarbonate, PC for short. It is obtained by interfacial polymerization of bisphenol G and phosgene or polycondensation with carbonate esters by transesterification method. PC is an amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow solid particle.
The relative density of pure resin is 1.2, the glass transition temperature is 145-150℃, the long-term use temperature is 130℃, the spontaneous combustion temperature is >550℃
