Impact
strength of extruded sheets from Asaflex™ blends - Asaflex™/GPPS
and Asaflex™/SC
By increasing the content of Asaflex™, sheet with superior impact strength can be obtained.
Higher transparency is generally obtained with the Asaflex™/SC* blends.
*SC™ Polymer: Styrenic Copolymer from PS Japan Corp.. Similar to Asaflex™ in refraction index, for sheet transparency significantly higher than attainable with any GPPS.
Small additions of Tufprene™
125 further increase the impact strength, as shown
here for blends containing 50 wt% Asaflex™.
Higher transparency is obtained with SC than with GPPS.
