Chlorinated Polyvinyl Chloride[edit | edit source]

Chemical structure of Chlorinated Polyvinyl Chloride

Chlorinated Polyvinyl Chloride (CPVC) is a thermoplastic polymer that is produced by chlorination of polyvinyl chloride (PVC) resin. It is widely used in various applications due to its excellent chemical resistance, high temperature resistance, and flame retardant properties.

Properties[edit | edit source]

CPVC has several unique properties that make it suitable for a wide range of applications. It has a higher chlorine content compared to PVC, which enhances its chemical resistance and thermal stability. CPVC can withstand higher temperatures, up to 200°C (392°F), without deforming or degrading. It also has excellent flame retardant properties, making it a preferred choice for fire safety applications.

Applications[edit | edit source]

CPVC finds extensive use in various industries and applications. Some of the common applications include:

1. Plumbing Systems: CPVC pipes and fittings are widely used in residential and commercial plumbing systems due to their corrosion resistance and ability to handle hot water.

2. Fire Sprinkler Systems: CPVC pipes are commonly used in fire sprinkler systems due to their flame retardant properties and ability to withstand high temperatures.

3. Chemical Processing: CPVC is used in chemical processing industries for the construction of tanks, pipes, and valves due to its excellent chemical resistance.

4. Electrical Conduits: CPVC is used for electrical conduits and cable insulation due to its flame retardant properties and high temperature resistance.

Environmental Impact[edit | edit source]

CPVC is considered to be a relatively safe and environmentally friendly material. It is not known to release any harmful substances during its use or disposal. However, like any other plastic, proper recycling and disposal methods should be followed to minimize its impact on the environment.
