Chlorinated polyvinyl chloride (CPVC) is widely used in various industries due to its excellent chemical resistance, thermal stability, and mechanical strength. One of its primary applications is in plumbing systems, where it is used to manufacture pipes and fittings for hot and cold water distribution. CPVC's ability to withstand higher temperatures compared to standard PVC makes it ideal for residential, commercial, and industrial water systems. It is also commonly used in fire sprinkler systems due to its flame-retardant properties and durability.

In the chemical processing industry, CPVC is utilized for piping and equipment that handle corrosive substances, such as acids, bases, and salts. Its resistance to chemical degradation ensures long-term performance in harsh environments. Additionally, CPVC is employed in the production of industrial fluid handling systems, including those for wastewater treatment and chemical manufacturing. In the food and beverage industry, CPVC is used for piping and equipment handling hot water and cleaning agents, providing non-contaminating and safe contact properties.

Another significant application of CPVC is in the fabrication of sheets, valves, and ducts for ventilation systems, particularly in environments requiring corrosion resistance and thermal stability. Its lightweight nature and ease of installation further contribute to its popularity in construction and industrial settings. Overall, CPVC's versatility and robust properties make it a critical material in various engineering and infrastructure applications.
