Asaflex™ 840

About
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 .&&
