CPVC is chloride modified from polyvinyl chloride (PVC) resin, is a new engineering plastics. After chlorinated PVC resin, the irregular of the molecular bonds increase, the polarity increased, make the solubility of the resin increase, the chemical stability increase , thereby enhancing the material resistance to heat, acid, alkali, salt, oxidants, etc. Improve the mechanical properties of the heat distortion temperature, chlorine content improved from 56.7% to 63-69%, Vicat softening temperature improved from 72-82 ℃ to 90-125 ℃, the maximum temperature up to 110 ℃, long-term use temperature of 95 ℃.
