CPVC PERFORMANCE

SEKISUI's unique raw material resin manufacturing technologies

CPVC is obtained by adding chlorine to PVC. SEKISUI's unique PVC polymerization and chlorination technology (heat chlorination manufacturing method) make it possible to manufacture chlorinated polyvinyl chloride of superior quality.

Superior mechanical strength

CPVC can be used for hot-water supply pipes up to 90°C, and it boasts high tensile strength even under high temperatures.

Heat resistance

CPVC's heat resistance is improved as a result of adding chlorine.

  • *HDT:Heat Deflection Temp.

Superior flame resistance

CPVC is a self-extinguishing resin, and so compared to other plastic ingredients it is a highly flame resistant, low smoke-producing material.

  • *LOI is the percentage of oxygen needed in the atmosphere to support the combustion of a material.

Superior from a hygiene perspective

When compared to other pipe material products, CPVC inhibits bacterial growth the most (no bacterial growth in 120 days in water piping).
