STYRON™ 487R-AMST Americas Styrenics Polystyrene, High Impact

Product Description

STYRON™487R-AMST is a high impact polystyrene with an excellent balance of flow, toughness, stiffness, and heat resistance as compared to other high impact polystyrene resins. It is appropriate for extrusion applications where stiffness and toughness combined with trimability are important. STYRON 487R can be used in deep draw thermoforming and injection molding applications.
