Description

Chlorinatedpolyvinylchloride CAS NO 68648-82-8 is a high-performance thermoplastic polymer produced by the post-chlorination of polyvinyl chloride (PVC), resulting in enhanced thermal stability and chemical resistance. This modification is critical for applications requiring superior performance under demanding conditions compared to standard PVC. It is an essential material for manufacturers in sectors such as industrial piping, chemical processing, and specialty coatings.

Application

• Industrial Piping Systems: Manufacture of corrosion-resistant pipes and fittings for hot water, chemical transport, and industrial waste systems.
• Chemical Processing Equipment: Used in the production of tanks, linings, valves, and ductwork that handle aggressive chemicals.
• Fire Sprinkler Systems: A key material for pipes in fire suppression systems due to its flame retardancy and heat resistance.
• Power & Utilities: Insulation for electrical cables and components requiring high thermal endurance.
• Specialty Adhesives & Coatings: Formulation of high-performance adhesives and protective coatings for metal and concrete.
• Automotive & Aerospace: Used in under-the-hood components and aircraft interior panels where flame resistance and low smoke emission are critical.
