Abstract:
A thermoplastic composition comprises, based on the total weight of the thermoplastic composition, 10 to 45 wt. % of a poly(etherimide); 35 to 90 wt. % of a poly(carbonate-siloxane); 0.5 to 20 wt. % of compatibilizer polycarbonate component comprising a poly(carbonate-arylate ester); up to 15 wt. % of an ultraviolet light stabilizer; and 0 to 30 wt. % of TiO2; wherein a sample of the composition has a notched Izod impact energy of at least 200 J/m at 23° C. measured in accordance to ASTM D256; and an at least 50% higher notched Izod impact energy value compared to the composition without the compatibilizer component measured in accordance to ASTM D256.
Abstract:
A railway component comprises a polycarbonate composition comprising: a first polycarbonate selected from a linear polycarbonate homopolymer, a branched polycarbonate, a poly(carbonate-bisphenol arylate ester), a poly(aliphatic ester-carbonate), or a combination thereof; a second polymer different from the first polycarbonate, the second polymer comprising a poly(carbonate-siloxane) copolymer, a polydialkylsiloxane, a silicone graft copolymer, or a combination thereof, wherein siloxane units in the second polymer are present in an amount of 0.3 to 3 wt. %, based on the total weight of the composition; and 10 to 40 wt. % of glass fiber, based on the total weight of the polycarbonate composition.
