Lubrizol’s CPVC compounds provide mid-range thermal performance and higher heat resistance than PVC. They can extend high temperature performance compared to PVC and maintain shape and color without deformation. Our CPVC compounds are an ideal replacement for standard vinyl solutions in certain exterior applications where heat distortion and dimensional stability can become a serious problem, particularly in dark colors.
Lubrizol’s CPVC compounds and resins offer improved fire resistance compared to PVC due to reduced flame spread, smoke development resistance and lower smoke density. They can offer a cost-effective solution for fire performance often reducing dependency on additional, costly additives.
