Description

Polycarbonate copolymer compositions for in-track components Citation of related applications The present application claims priority and equity from european patent application number 21162286.5 filed 3/12 of 2021, the contents of which are incorporated herein by reference in their entirety. Technical Field The present disclosure relates to compositions for in-train (interior) components and particularly seat components and cladding (cladding) having low smoke density and low heat release (HEAT RELEASE). Background Coordinated fire standards (i.e., EN-45545) for rail applications place stringent requirements on the allowable heat release, smoke density, and toxicity and flame spread characteristics of materials used in rail applications in the european union. As set forth in the requirements of EN-45545, the "risk levels" (HL 1 through HL 3) have been specified, reflecting the degree of probability of personal injury due to fire. The level is based on residence time and is related to the operational and design categories. HL1 is the lowest risk level and is generally applicable to vehicles that operate under relatively safe conditions (easy evacuation of the vehicle). HL3 is the highest risk level and represents the most dangerous class of operation/design (difficult and/or time-consuming evacuation of vehicles, e.g. in underground rail vehicles). EN-45545 classified the products into 26 requirement sets (R1-R26). R1 includes horizontal and vertical interior surfaces and R6 includes a passenger seat shell and a cover. For each product type, different test requirements for the hazard class are defined. The test methods for various hazard classes, as well as smoke density and maximum heat release rate values in the european rail standard EN-45545 (2013) for R6 applications are shown in table 1A. TABLE 1A For R1 applications, the test methods for various hazard classes, as well as smoke density, maximum heat release rate values, and critical heat flow when extinguished (CRITICAL HEAT flux at extinguishment) in European rail standard EN-45545 (2013) are shown in Table 1B. TABLE 1B Polycarbonates are useful in the manufacture of articles and components for a wide range of applications, from automotive parts to electronic appliances. Due to their wide range of applications, particularly in rail internals (rail internals), it is desirable to provide polycarbonate compositions having properties meeting or exceeding the requirements set forth in EN-45545. However, it is particularly challenging to manufacture articles that meet these criteria and have good mechanical properties (including high stiffness, high strength, good impact, and good processability). Thus, there remains a need for polycarbonate compositions having a combination of low smoke, low heat release, low toxicity, and low flame spread properties. It would be a further advantage if polycarbonate compositions could be prepared at low material cost, with ease of manufacture, and with desirable mechanical properties. Disclosure of Invention The above and other deficiencies in the art are met by a polycarbonate composition comprising a polycarbonate comprising a homopolycarbonate or a combination of a homopolycarbonate and a brominated polycarbonate, a poly (carbonate-siloxane) having a siloxane content of 30 to 70 weight percent based on the total weight of the poly (carbonate-siloxane), the poly (carbonate-siloxane) being present in an amount effective to provide 1 to 10 weight percent of the total siloxane based on the total weight of the composition, 11 to 25 weight percent of a reinforcing composition comprising 10 to 24 weight percent glass fibers, and 1 to 10 weight percent of a mineral filler comprising talc, kaolin, calcium carbonate, wollastonite, or a combination thereof, optionally an organophosphorus flame retardant in an amount effective to provide up to 1.5 weight percent phosphorus, optionally up to 10 weight percent of an additive composition, wherein the sum of the amounts is 100 weight percent based on the total weight of the polycarbonate composition. The above and other deficiencies in the art are met by a polycarbonate composition comprising poly (ester-carbonate-siloxane), poly (aliphatic ester-carbonate), poly (ester-carbonate-siloxane), brominated polycarbonate, poly (ester-carbonate), poly (phthalate-carbonate), or a combination thereof and optionally, a homopolycarbonate, poly (carbonate-siloxane) present in an amount effective to provide 1 to 10 weight percent total siloxane, based on the total weight of the composition, 11 to 25 weight percent of a reinforcing composition comprising 10 to 24 weight percent glass fibers, and 1 to 10 weight percent mineral filler comprising talc, kaolin, calcium carbonate, wollastonite, or a combination thereof, optionally, an organophosphorus flame retardant in an amount effective to provide up to 1.5 weight percent phosphorus, and optionally, up to 10 weight percent additive composition, wher
