"PVC-C can safely be used to carry hot, corrosive liquids"

Chlorinated Polyvinyl Chloride (PVC-C) is a modified PVC with additional high temperature strength. It has been developed to handle hot, corrosive liquids at working temperatures up to 100°C, whilst offering the ease of installation of cold solvent welded jointing.

PVC-C is inert to many mineral acids, bases, salts, paraffinic hydrocarbons, halogens and alcohols. It will not support combustion and is rated as self extinguishing. The low thermal conductivity of the material reduces moisture condensation on water lines, and will maintain the temperature of fluids with minimal insulation.

With a similar working temperature range to polypropylene, PVC-C has greater rigidity and lower thermal expansion, making it particularly suitable for above ground process pipework.
