PS Polystyrene Testing

Polystyrene (PS) is a transparent synthetic polymer produced by the polymerization of styrene. Polystyrene most commonly comes in two forms — general purpose or crystal polystyrene and high impact polystyrene. These two forms of PS exhibit different physical properties and have different applications as a result. General purpose polystyrene is used in applications such as cutlery, food packaging, medical and diagnostic labware, office accessories, housewares and insulation panels for building and construction. High impact polystyrene has the advantages such as ease of processing, good dimensional stability, high impact strength, and rigidity. It is used in applications like trays, containers, medical components, and packaging.

STEMart validates the quality and performance of PS materials to assist manufacturers in optimizing their manufacturing processes, in the search for substitute materials and in solving failure problems on PS materials.
