CPVC resin is produced by chlorination modification of PVC (polyvinyl chloride) resin, making it a new engineering plastic with excellent performance and broad application prospects. It appears as a white or light yellow, odorless, tasteless, non-toxic loose powder.

Key Properties & Modifications

· Molecular Structure: Chlorination increases molecular chain irregularity and polarity, enhancing the resin’s solubility and chemical stability.

· Chemical Resistance: Improved tolerance to chemical media such as acids, alkalis, salts, and oxidizers.

· Thermal & Mechanical Performance:

 Chlorine content rises from 56.7% to 63–72%, significantly increasing heat resistance.

 Vicat softening temperature increases from 72–82°C to 100–125°C, with a maximum service temperature of 110°C and long-term service temperature exceeding 95°C.

These modifications make CPVC an ideal material for high-temperature and corrosion-resistant applications, such as industrial pipelines, electrical insulation, and automotive components.

CPVC Applications

CPVC is primarily used in the production of pipes for conveying hot water and corrosive media, as well as pipe fittings for water supply systems, filtration materials, dehydrators, and electrical/electronic components.
