CPVC resin plates made of poly chlorofluoroethylene (PVC) resin modified chloride obtained is a new engineering plastics. CPVC board products for dark gray or light gray, tasteless, odorless, non-toxic loose particles or powder. After chlorinated PVC resin, the molecular bond irregularity increases, the polarity increases, the solubility of the resin increases, increased chemical stability, thereby enhancing the heat resistance of the material, acid, alkali, salts, oxidants, etc. corrosion. CPVC board to improve the mechanical properties of the heat distortion temperature values, the chlorine content from 61.7% up to 72-75%, Vicat softening temperature from 60-72 ℃, (up to 85-96 ℃), the maximum temperature up to 112 ℃, long-term use temperature of 90 ℃. Therefore, CPVC board is a promising application of new engineering plastics. Irregular increase in polarity increased CPVC plate molecular bonds, the solubility of the resin increases, increased chemical stability, thereby enhancing the heat resistance of the material, acid, alkali, salt, oxidants such as corrosion, improve the value of heat distortion temperature mechanical properties. Compared with the general PVC, a more excellent high temperature, excellent corrosion resistance, dimensional stability, ease of processing, excellent flame resistance and other characteristics.
