CPVC resin, an advanced engineering material, is made from modified PVC resin by
chlorination. This product is white or light yellow particles or powder which is tasteless,
odorless and non-toxic. After the chlorination of PVC resin, the irregularity and polarity
of molecule bond increase, thus the solubility of the resin and its chemical stability increase.
Corrosion resistance of heat, acid, alkali, salt and oxidizer also witnesses an improvement.
The mechanical property of the thermal deformation temperature improves accordingly. The
content of chlorine sees a growth from 56.7% to 63%-69%. Its Vicat Softening Temperature
increases from 72-82C to 90-125C with a maximum use of temperature and long time
using temperature reaching 110 ℃ and 95 ℃ respectively. Hence, CPVC is a kind of advanced
engineering plastic with rosy prospect.
Application
Pipe and fitting for hot and cold water, heat- and corrosion- resistant pipe and fitting used in
chemical field, CPVC pipe and fitting for buried high voltage cable, fire hoses and fittings in
places with strict fire safety requirements, pipe and fitting for crude oil.
