Product introduction
Chlorinated polyvinyl chloride (CPVC) is a synthetic polymer material made from a special brand of polyvinyl chloride (PVC) resin through aqueous phase chlorination reaction. Appearance: white or slightly yellow flowable solid powder. In addition to possessing many of the excellent properties of PVC, CPVC has greater corrosion resistance, heat resistance, solubility, flame retardancy, and mechanical strength than PVC. CPVC is a new material with excellent performance and is known as Widely used in construction, chemical industry, metallurgy, shipbuilding, electrical appliances, textiles and other fields.

Product Details
Chlorinated polyvinyl chloride is a new type of engineering plastic produced by chlorination modification of polyvinyl chloride (PVC) resin. The product is white or light yellow, tasteless, odorless, non-toxic loose granules or powder. After PVC resin is chlorinated, the irregularity of the molecular chain arrangement increases and the polarity increases, which increases the solubility and chemical stability of the resin, thus improving the material's heat resistance and resistance to acids, alkalis, salts, oxidants, etc. corrosion properties. The Vicat softening point of CPVC is about 40C higher than that of PVC, so the long-term use temperature of its products can reach 98C. CPVC products have good corrosion resistance and are resistant to corrosion by most acids, alkalis, salts and other chemicals. Therefore, CPVC is a new engineering plastic with broad application prospects.

Product application
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.
Transportation and packaging
common problem
1. Can you provide samples to customers for free?
Yes, we can provide free samples to help you with the test, but we need to charge the freight.
2. How to order products?
You can ask us about product prices and product questions online, and we will reply to your questions as soon as possible.
3. Does the testing process provide technical assistance?
Yes, we have a professional technical team that can assist you in sample testing and provide technical assistance to customers.
4. Some product transportation problems:
For the samples you need, we can deliver them to you through international express delivery such as Shunfeng, Deppon, etc. For bulk goods purchased in bulk, we will ship them to you by sea. You can inform us in advance of your nearest port, and we promise to deliver them to you.
5. How to save the product?
During loading and unloading, keep it clean to prevent exposure to the sun, rain, high temperature and humidity, and to avoid damage to the package. It shall be stored in a cool, dry warehouse without direct sunlight and at a temperature lower than 40 ºC for two years. After two years, it can still be used after passing the performance inspection.
6.Are you a production company or a trader?
Hello, we are the manufacturer.
