Our polystyrene products cover the whole range of common applications from General Purpose Polystyrene (GPPS) to High Impact (HIPS) for markets such as consumer products, packaging, building/construciton, and the electrical/electronic market. Our range of crystal polystyrene products includes low melt flow, rigid high heat resins for foam and oriented polystyrene (OPS) applications to high melt flow injection molding general purpose resins. Our impact products range from low melt flow, medium impact to high melt flow, super high impact resins and cover the entire range of viscosity and toughness requirements. In all cases our technical and sales services can provide customers with assistance to choose the best fitting grade for their use.
