CORZAN® CPVC (Chlorinated Polyvinyl Chloride) Type 4. Grade 1

This material’s physical properties (at 73°F or 23°C) and chemical resistance are very similar to those of PVC. Its major advantage over PVC is the ability to handle hot corrosive liquids in service temperatures up to 180°F (82°C).

The molded version of Corzan is Temprite®, which like Corzan, is manufactured by Lubrizol. Plast-O-Matic uses 100% Corzan brand CPVC in the manufacture of its products.

CPVC is joined by solvent cementing, threading, or flanging. It must be done by a professional, properly trained in joining CPVC.
