Abstract:
A thermoplastic composition comprising, based on the total weight of the thermoplastic composition, 5 to 30 wt. % of a poly(arylene ether-sulfone); and 50 to 95 wt. % of a polycarbonate component comprising a poly(carbonate-siloxane) and optionally a polycarbonate homopolymer; wherein a sample of the composition has a notched Izod impact value of greater than or equal to 30 kJ/m2; a tensile yield strength retention of 80% and higher after exposure of an ISO tensile bar for 24 hours to sunscreen under 0.5% strain compared to a non-exposed reference; and an elongation at break retention of 80% and higher after exposure of an ISO tensile bar for 24 hours to sunscreen under 0.5% strain compared to a non-exposed reference.
