GPPS (general-purpose polystyrene) for clear packaging, disposables, light diffusers and XPS foam board. Send an RFQ.
GPPS, also called crystal polystyrene, is fully transparent, rigid and easy to process. It is brittle, so it is used where clarity and stiffness matter more than impact strength.
Grades differ mainly in flow and heat resistance.

Usually no drying needed. Typical melt temperature 180–240 °C. Avoid sharp corners and high ejection force, as GPPS cracks easily.
General guidance only; follow the producer's TDS for each grade.
Yes. Blends are common in sheet and thermoforming to tune clarity, stiffness and impact strength.
