CPVC Resin for Hot & Cold Water Pipes & Fire Sprinkler Systems | China Suppliers & Factory
Performance Characteristics
The Vicat softening point of CPVC is about 40 degrees higher than that of PVC, allowing the long-term use temperature of its products to reach 98 degrees.
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).
