WEB EXCLUSIVE: New Lexan FST3403 PC copolymer from Sabic Innovative Plastics, Pittsfield, Mass., is hailed as the first thermoplastic material developed specifically for railroad seat-back shells and side covers that meets the strictest fire-safety requirements of the new European CEN/TS 45445-2R5 standard, which will go into effect in two years.

Lexan FST (flame-smoke-toxicity) copolymer achieves the highest possible hazard-level rating (HL3) under the new standard due to its exceptional performance in heat-release, smoke-density, and smoke-toxicity tests, documented by independent laboratory testing. It also has high flow for injection molding large parts with excellent aesthetics and impact strength. Says Ilknur Gur, general manager of Sabic Innovative specialty business in Europe, “Our new Lexan FST3403 copolymer enables customers to continue to use thermoplastics in their seat-back shells and side covers instead of having to revert to metal or thermosets that can inhibit design flexibility and potentially add weight and costs from secondary operations.”
