China CPVC Resin for Hot and Cold Water Pipes and Fire Sprinkler Systems - Reliable Suppliers & Factory

Chlorinated Polyvinyl Chloride (CPVC) is a high-performance synthetic polymer derived from a specialized grade of Polyvinyl Chloride (PVC) resin through a unique aqueous chlorination process. This versatile material features a white or slightly yellow flowable solid powder, offering non-toxic and odorless properties. As a leading CPVC manufacturer in China, our factory ensures top-quality production to meet diverse industrial needs. We are committed to providing reliable CPVC solutions, making us the preferred choice among suppliers worldwide

Product Details

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).

Characteristics and Selection of Conventional Brands

Frequently Asked Questions (FAQ)

Q: What is the maximum long-term use temperature of CPVC products?

A: The long-term use temperature of CPVC products can reach up to 98°C. This is because the Vicat softening point of CPVC is approximately 40 degrees higher than that of standard PVC.

Q: How is CPVC classified?

A: CPVC is divided into two primary classifications based on the processing method: extrusion type (Grade J) and injection type (Grade Z).

Q: What are the differences between CPVC grades J-700 and Z-500?

A: J-700 is an extrusion grade used for manufacturing structural materials like plates, pipes, and corrugated boards. Z-500 is an injection grade designed for making various pipe fittings, chemical tower packing, and other injection-molded components. Both grades offer excellent flame retardancy, heat resistance, and corrosion resistance.

Q: What are the standard packaging specifications for CPVC?

A: The product is sealed inside plastic bags and then protected by an outer polypropylene bag. Each package has a net weight of 25±0.1kg.

Q: What are the storage requirements for CPVC?

A: CPVC should be stored in a dry, well-ventilated warehouse. It must be protected from moisture and direct sunlight exposure. During transit, it is critical to prevent pollution, rain, heat, and direct sun exposure, even though the product is classified as non-hazardous.
