By increasing the Asaflex™ content in Asaflex™/GPPS blends, transparent sheet with low temperature impact strength can be obtained, without losing the transparency of GPPS. For applications not requiring transparency, Tufprene™ is more effective for increasing the impact strength.

Comparison of low temperature impact strength (-30°C)

Formulation components	Component ratio	Sheet thickness (mm)	Dart impact strength (J/m)	Haze (%)
Asaflex™ 835/GPPS	50/50	0.30	1	1.3
Asaflex™ 835/GPPS	70/30	0.30	7	0.7
