Main uses:
Hot/cold water pipes and fittings: CPVC has good heat resistance and can be used at 82℃ for a long time with good thermal insulation. It can be widely used in civil and industrial heat-resistant pipes and parts, such as hot and cold water pipes, fittings, valves and other heat-resistant shaped parts of towers.
Corrosion-resistant pipes, containers and components: CPVC has good resistance to acid, alkali, salt and other chemicals corrosion, in the chemical industry, water treatment, marine engineering, light industry, electronics and mining industries are widely used. Processed into pipes of different caliber, it can be used for conveying process media, processed into plates for making towers and tanks, etc. It can also be used to make corrosion-resistant pipe fittings, valves, rods, or other materials construction materials, CPVC has good flame retardant and smoke suppression properties, high strength, and good abrasion resistance. CPVC has good performance in making various kinds of fire fighting pipes, door and window profiles, flame retardant flooring, etc. CPVC can be used with foaming agent to make foaming material for building thermal insulation with good heat insulation effect and flame retardant and smoke suppression.
Sleeving for power transmission: CPVC is used to make buried high-voltage power cable transmission sleeving, which has outstanding advantages over PVC in terms of heat resistance, flame retardancy and insulation. It can be widely used in urban power grid reconstruction.
Roofing and siding materials: CPVC has outstanding anti-ultraviolet and atmospheric aging resistance, high strength, processing roof panels and exterior wall protection materials, not easy to aging, long service life.
Plastic Modifier: CPVC has good compatibility with general polar plastic materials and can be used for modification of other plastics to improve their heat resistance and flame retardancy.Corrosion-resistant man-made fibers: CPVC has high melt strength and can be drawn to prepare fishing nets, filter cloths, filters, parachutes, etc. to make heat-resistant sheets for electrical and electronic and other applications of shaped parts.
