Rigid PVC is used in a broad range of applications, including:
|Advantages||Rigid PVC is a versatile thermoplastic resin that’s rigid and tough under ambient conditions. To allow injection molding, additives are mixed with PVC, including stabilizers, lubricants, processing aids, pigments, impact modifiers and fillers. Some of its other advantages include:
Typically, lower molecular weight grades of this resin are used in injection molding as the high molecular weight grades are more difficult to process. It’s very important to process the material at the correct melt temperature to avoid decomposition and production of hydrochloric acid. Other limitations of Rigid PVC include:
