UPVC pipe properties

UPVC tube to PVC resin for carrier, in weakened resin molecular chain between of gravity Shi has sense temperature accurate, and timing melting, and quickly absorption additives of effective components, excellent characteristics, while, used world famous calcium zinc composite type hot stable agent, in resin by high temperature and melting of process in the can capture, and inhibit, and absorption in the and hydrogen chloride of prolapse, and poly en structure for double bond added into reaction, replacement molecular in the lively and not stable of chlorine atomic. Effectively scientific control resin in molten state of degradation and oxidation.
