Introduction
Chlorinated Polyvinyl Chloride (CPVC) is a synthetic polymer material made from a special brand of Polyvinyl Chloride (PVC) resin through aqueous chlorination reaction. Its appearance is a white or slightly yellow flowable solid powder and it is non-toxic and odorless.
Performance Characteristics
1、The use temperature of the product increases
The Vicat softening point of CPVC is about 40 degrees higher than that of PVC, so the long term use temperature of its products can reach 98 degrees.
2、Good corrosion resistance
The product can withstand the corrosion of most acids, alkalis, salts, and other chemicals.
Application field
CPVC can be widely used in fields such as petroleum, chemical industry, building materials, shipbuilding, electrical appliances, printing and dyeing, electroplating, food, etc. It is mainly used for manufacturing heat-resistant and corrosion-resistant pipes and accessories, residential pipe (hot water pipe) systems, communication pipe systems, sewage pipe systems, etc.
CPVC classification
Divided into extrusion type (J) and injection type (Z).
