Sabic Innovative Plastics has developed new polycarbonate grades in resin and sheet form for rail seating applications to meet fire safety requirements under the CEN/TS 45445 standard. The Saudi group's new Lexan FST3403 PC copolymer is an injection moulding grade for train seat back shells and side covers. The grade is being offered two years before the European CEN/TS 45445 standard goes into effect. The copolymer was tested by the Currenta Institute in Germany according to the requirements of the standard and was certified to comply with hazard level 3, the most challenging level to achieve. Currenta tested the material for heat release under ISO 5660-1 and for smoke density and toxicity under ISO 5659-2. Sabic said the material also provides high flow capabilities meaning that large parts, such as seat back shells, can be injection moulded without surface defects. It can also be moulded in tooling that is typically used for PC/acrylonitrile butadiene styrene (ABS) materials.
