Three new PC products specifically designed for use in railcar interiors are newly available from SABIC, Pittsfield, Mass.
Included is injection molding grade Lexan FST3002, which features high-flow properties and meets the R6-HL2 requirements for fire safety in seating components such as seat base and back shells and seating side panels. It is said to enable the design and production of large parts with consistent surfaces with no marks, stains or flowline.
Lexan KH6500 PC and KH6200 sheet grades are SABIC’s new anti-graffiti PC products. They meet the requirements of current German rail standard DIN 5510-2:2009 and reportedly offer users a non-chlorinated and non-brominated material supporting their sustainability efforts. Both grades comply with French NF F 31-112 anti-gravity norm, reportedly offering outstanding chemical resistance against graffiti and cleaning agents. The new sheet products are poised as a cost-efficient alternative to PVC, polyester, vinyl ester or phenolic fiber-reinforced plastics used in many interior train applications including interior panels, window frames, ceilings and other large interior parts.
KH6500 sheet can be used for seats, tables and carriage walls. It complies with the US National Fire Protection Association fire safety norm NFPA 130 for passenger rail car walls and ceilings. Its high stiffness reportedly results in both excellent impact performance at low temperatures (ductility down to -4 F/20 C) and thermoforming performance at lower temperatures compared to standard PC materials. KH6200 sheet has an S4/SR2/ST2 rating according to the German DIN 5510 norm at 3-5 mm (0.118-0.197 in.) and is said to offer an attractive cost-benefit balance in less-demanding applications such as cladding. Like KH6500, it offers excellent impact performance at low temperatures and thermoforming performance at lower temperatures.
