High-Quality CPVC Resin for Hot & Cold Water Pipes and Fire Sprinkler Systems from China Suppliers and Factory
Performance Characteristics
1. Increased Use Temperature
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.
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).

Frequently Asked Questions (FAQ)
Q1: What is the maximum long-term use temperature for CPVC products?
A: The long-term use temperature of CPVC products can reach up to 98 degrees. This is because the Vicat softening point of CPVC is approximately 40 degrees higher than that of standard PVC.
Q2: What kinds of chemicals can CPVC products resist?
A: CPVC offers excellent corrosion resistance and can withstand degradation from most acids, alkalis, salts, and various other chemicals.
Q3: What are the main applications of CPVC?
A: CPVC is widely used in petroleum, chemical processing, building materials, shipbuilding, electrical appliances, printing and dyeing, electroplating, and the food industry. It is primarily utilized for heat-resistant and corrosion-resistant pipes, residential hot water systems, communication conduits, and sewage piping.
Q4: What is the difference between J-700 and Z-500 CPVC grades?
A: J-700 is an extrusion-type grade used mainly for structural materials like plates, pipes, and corrugated boards. Z-500 is an injection-molding grade designed for components such as pipe fittings and chemical tower packing.
Q5: How is CPVC packaged and what are the storage requirements?
A: CPVC is sealed in plastic bags and packed in outer polypropylene bags, weighing 25±0.1kg each. It must be stored in a dry, ventilated warehouse. During transit, it should be protected from moisture, direct sunlight, rain, heat, and pollution.
Q6: Is CPVC classified as a hazardous material for transport?
A: No, CPVC is officially classified as a non-hazardous material.
