Injection- and blow-molding grade. For transparent products with superior impact strength. Blended with GPPS (general-purpose polystyrene) or SC*, for films with good thermal stability. Capability for profile-extrusion products. It is supplied in pellet form.

Cosmetics caps, stationery goods, other consumer goods. Blended with GPPS for PSP* laminate films and IC magazine rails, and with SC* for shrink films.

* Styrenic copolymer from PS Japan Corp. similar to Asaflex™ 825 in refraction index, resulting in blends that provide sheet transparency significantly higher than attainable with any GPPS.
