FLAME RETARDANT POLY(SILOXANE) COMPOSITIONS, METHODS OF MANUFACTURE, AND ARTICLES FORMED THEREFROM

摘要

A railway vehicle component, wherein the component is a partition or a light cover, and wherein the component is molded or formed from a thermoplastic polymer composition comprising: a siloxane-containing copolymer in an amount effective to provide a total of 0.2 to 6.5 wt% of siloxane units based on the total weight of the polymers in the thermoplastic polymer composition, a bromine-containing polymer in an amount effective to provide 9 to 13 wt% of bromine, based on the total weight of the polymers in the thermoplastic polymer composition, and optionally a third polymer, wherein the wt% of the siloxane-containing copolymer, the bromine-containing polymer, and the optional third polymer, sum to 100 wt%, and 0.05 to 10 wt% of a light diffuser additive, based on the total weight of polymers in the thermoplastic polymer composition.
