Abstract:
A aircraft component comprises a polycarbonate composition comprising: a first polycarbonate selected from a polycarbonate homopolymer, 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 the polycarbonate composition in an amount of 0.3 to 3 wt. %, based on the total weight of the polycarbonate composition; and 10 to 50 wt. % of glass fiber, based on the total weight of the polycarbonate composition.
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.
