- Commodity name: CPVC Resin
CPVC resin is a functional polymer material obtained by chlorination of PVC resin. It is in white powder form, non-toxic and odorless.

CPVC resin is a functional polymer material obtained by chlorination of PVC resin. It is in white powder form, non-toxic and odorless. The chlorination changes the original molecular chain structure, thus giving CPVC a series of excellent properties. CPVC resin is widely used in the fields such as industry, construction, transportation and new energy, has been highly favored by users due to its excellent comprehensive performance.
Sundow Material takes 25m³ pressure-resistant enamel reactor, equipped with efficient stirring system and frequency conversion device; through the DCS control system, the entire production process is automatically controlled; the upstream raw material supply is stable; the company is staffed with highly qualified R&D and inspection personnel and equipped with advanced facilities to ensure the high product quality, homogeneity and stability. At present, Sundow Material has an annual production capacity of 30,000 tons of CPVC resin. Sundow Material occupies a large share of the domestic CPVC market, and has exported its CPVC products to over 30 countries and regions, including India, Bangladesh, the Middle East, South Korea, North America, and South America.
