Sheet grade. Blended with SC*, for highly transparent sheets. It is supplied in pellet form.

Blended with SC* for transparent blister packs and other sheets, with GPPS for frozen dessert cups and other containers, and with GPPS/Tufprene™ to obtain PS sheets for food containers and other applications.

* Styrenic copolymer from PS Japan Corp. similar to Asaflex™ 815 in refraction index, resulting in blends that provide sheet transparency significantly higher than attainable with any GPPS (general-purpose polystyrene).
