Description

Polystyrene (PS) is a clear, colorless polymer used extensively for low-cost applications. It is available commercially in both pellet and sheet form. The most serious deficiencies are low impact strength, poor weatherability and poor chemical resistance. Numerous modified grades which seek to correct these shortcomings are commercially available.
