GPPS C12 is a high melt flow crystal polystyrene designed for good processability and short injection molding cycles.

GPPS C13 is a crystal polystyrene that has excellent clarity with a slight blue tint. It has improved cycle times in hard to fill parts. This resin is food contact compliant.

GPPS C2 is a high molecular weight, low melt flow, high heat crystal polystyrene. This polymer makes superior foam and oriented polystyrene sheet (OPS).

GPPS C20 is a high flow, high heat crystal polystyrene. The very low viscosity of this grade and its heat resistance makes it particularly suitable for the production if extrusion foam board.

GPPS C8 is a general purpose polystyrene grade with a good flow characteristic and improved heat resistance.

HIPS C13 is a high melt flow, high impact polystyrene specially designed for hard to fill injection molding applications. The material is targeted for large parts, thin wall parts, or molds with complex runner and gate systems. The high flow material aids production of stress free parts.

HIPS REPRO 3-5 Black combines the good stiffness properties of polystyrene, with enhanced impact properties gained by the addition of impact modifiers, usually butadiene rubber. An amorphous resin, HIPS has low post-molding shrinkage, good melt strength, and a wide melt processing window, making the resin ideal for many sheet and thermoforming applications.
