Polystyrene (PS) Plastics
General purpose polystyrene is the low-cost member of the plastics family. Properties of the amorphous polymer include hardness, rigidity, optical clarity, dimensional stability, and excellent processibility.
HIPS – High-impact polystyrene, is generally recognized as the best styrenic material for load bearing applications. Typical applications include food packaging (cups, lids, take-out containers), house wares, office products, and video and audio cassettes. Ignition-resistant plastic grades are used in radio and TV housings.
SB – Styrene-Butadiene are block plastic copolymers that combine transparency and high impact strength. Packaging is a major market in items such as cups, lids, trays, and clamshells for the fast-food industry.
EPS – High-impact polystyrene, is generally recognized as the best styrenic material for load bearing applications. Typical applications include food packaging (cups, lids, take-out containers), house wares, office products, and video and audio cassettes. Ignition-resistant plastic grades are used in radio and TV housings.
SAN – Acrylonitrile are copolymers that are transparent, amorphous materials with higher heat and chemical resistance than crystal polystyrene plastic. SAN is injection molded into such products as dishwasher-safe housewares, refrigerator shelves, medical devices, oven caps, connectors for PVC tubing, and lenses.
