Röchling Engineering Plastics, Haren, Germany, has launched two new PIN flame retardant plastics certified to the EU railway standard EN 45545-2.
Using non halogenated flame retardants, enables to both achieve demanding fire safety requirements (self-extinguishing, UL94-V0 3 mm) and low smoke and low toxic gases in case of fire (R11 hazard level HL3). Durostone® UPM S13 LST is a glass-fibre reinforced unsaturated polyester resin and Polystone® MK FL is a thermoplastic polyester. Both offer low density (for lightweight components) and high strength, as well as electrical material performance characteristics. These PIN FR plastics add to Röchling’s range of railway standard compatible materials which include SUSTAMID6 FR and MAYWOflamm®.
