UPVC pipe is made of polyvinyl chloride resin as a carrier. It has excellent characteristics such as accurate temperature sensing, timed melting and rapid absorption of the active ingredients of the additive when weakening the attraction between the molecular chains of the resin. At the same time, the world famous calcium-zinc composite heat stabilizer is used. During the process of high temperature and melting of the resin, the neutralization and absorption of hydrogen chloride can be captured, suppressed, and absorbed, and a double bond addition reaction with the polyolefin structure is performed to replace the active and unstable chlorine atoms in the molecule. Thereby effectively controlling the catalytic degradation and oxidative decomposition of the resin in a molten state.
