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.

PTFE – polytetrafluoroethylene is extremely heat-resistant and has outstanding chemical resistance, being inert to most chemicals. Its coefficient of friction is lower than that of any other plastic, and it can be used unlubricated.

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.
