What is the difference between Corzan CPVC and PVC?
CPVC is the result of the post chlorination of PVC. The level of chlorine is increased from 56-57%, up to as high as 74%, although typically most commercial CPVC resins contain 63 to 69% chlorine. This increase in chlorine level raises CPVC’s maximum operating temperature to 200°F, over PVC’s maximum operating temperature of 140°F. In terms of chemical resistance, PVC and CPVC are very similar.
