Polyvinyl chloride commonly abbreviated PVC, is one of the most widely used plastics for a variety of applications. The rigid form of PVC is available in sheet, rod and machined/fabricated shapes and offers excellent chemical and corrosion resistance. Specialty grades are available with enhanced heat resistance or added flexibility.

ACI offers four types of solid pvc sheet: See-thrus and three mechanical grades: Type I, Type II and CPVC. The see-thrus include clear, transparent and translucent colors. The see-thrus are intended for chemical resistant glazing and displays that require a durable material.


Types I, II and CPVC are opaque and are intended for tough industrial applications.


All of these materials offer good chemical resistance and fire ratings (UL-94V-0) considered self-extinguishing. Type I typically offers the highest chemical resistance. Type II relaxes chemical resistance in return for greater impact resistance. Type II is suited for applications that require thermoforming or where the finished product is subject to shock or physical abuse. The sustained operating temperature for I and II is 140° F and CPVC is 180° F.


All of these products offer excellent chemical resistance and fire rating. Some notable differences between the products follow:


Clear PVC                          Type II                           CPVC

Light Transmission             Thermoformable            Higher Heat Stability
