Asaflex 840
苯乙烯-丁二烯-苯乙烯嵌段共聚物
AKelastomers
产品说明：
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 .
