Polifil® RP-HIPS

Reprocessed High Impact Polystyrene

Polifil® RP-High Impact Polystyrene (HIPS) 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...
