SABIC’s Innovative Plastics business recently announced new LEXAN FST3403 (flame-smoke-toxicity) polycarbonate (PC) copolymer, the first thermoplastic solution specially for rail seat back shells and side covers, to meet the strictest fire safety requirements under the CEN/TS 45445 standard. Now commercial a full two years before this European standard goes into effect, the new high-performance copolymer achieved the highest possible hazard level rating (HL3) under CEN/TS 45445-2 R5.
According to the company, in addition to its exceptional heat release, smoke density and toxicity performance, documented by independent laboratory testing, the LEXAN FST copolymer delivers high flow properties for injection molding large parts with excellent aesthetics and impact strength. Besides, it can be custom colored, which avoids the need for secondary painting.
LEXAN FST3403 copolymer was tested by the Currenta Institute in Germany according to the requirements of CEN/TS 45445-2 R5 for seat back shells and side covers. The facility certified that LEXAN FST3403 copolymer complies with the requirements of HL3. Apart from that, Currenta tested the material for heat release under ISO 5660-1 and for smoke density and toxicity under ISO 5659-2.
“Our new LEXAN FST3403 copolymer enables customers to continue using thermoplastics in their seat back shells and side covers instead of having to revert to traditional metal or thermosets that can inhibit design flexibility and potentially add weight and costs from secondary operations. This industry-leading technology greatly simplifies and accelerates compliance with the new European standard,” said Ilknur Gur, general manager, Specialty Business in Europe, Innovative Plastics.
