Injection molding, inflation molding, and sheet extrusion grade. Blended with GPPS (general-purpose polystyrene) or SC*, for products with well-balanced performance characteristics and good thermal characteristics. It is supplied in pellet form. In blends with GPPS, for PSP* laminate films. In blends with SC, for shrink films and other products. * Styrenic copolymer from PS Japan Corp. similar to Asaflex™ 840 in refraction index, resulting in blends that provide sheet transparency significantly higher than attainable with any GPPS . |
