1. An article comprising a thermoplastic composition, wherein the article is a rail car interior article or an airplane interior article and the thermoplastic composition consists of 70 to 99 wt % of a polyphenylene ether sulfone, 1 to 30 wt % of a resorcinol based silicone aryl polyester carbonate copolymer, based on the total weight of the composition, and optionally a metal oxide, fluoropolymer, boron compound, brominated flame retardant, antioxidant, colorant, light stabilizer, optical brightener, UV absorber, flow aid, mold release agent, reinforcing filler, or a combination thereof, wherein greater than or equal to 50 mol % of resorcinol based silicone aryl polyester carbonate copolymer repeating units are ester units derived from resorcinol, based on the total molar amount of all repeating units in the polymer and wherein the blend comprises less than 1 weight percent polycarbonate, based on the total weight of the composition, and the composition has a FAR 25.853 peak heat release of less than 50 KW/m2, a time to peak heat release of greater than or equal to 120 seconds, and a melt volume viscosity rate (MVR) at 300° C. using a six minute equilibration time, with 6.7 Kg, as measured by ASTM D1238, of greater than or equal to 2.0 cc/10 minutes. |
