Description & Properties of CPVC

Many people know of PVC; but what is CPVC? CPVC is related to PVC, and are similar in a few ways, but should not be used interchangeably. CPVC is altered by a chlorination reaction that increases the chlorine content of the material.

This change to the material allows it to withstand a wider range of temperatures. Where PVC has a limit of 140° F, the CPVC can withstand temperatures up to 200° F allowing for a wider range of field applications.

  • Typically comes in a light grey color
  • Suitable for hot water applications
  • Cost for CPVC is more that regular PVC, but still cost effective overall
  • We advise to check our free plastics handbook to check for specific chemical comparability
  • Along with PVC, CPVC is susceptible to stress cracking
  • Good Insulation properties
  • Lightweight
  • Good resistance to corrosion and deposits
  • Material is widely available in large selection of sizes to offer more design possibilities
  • Chlorine and chloramine resistance
