Flame-Resistant Plastics for Railway Engineering
Now Certified to the Relevant Requirements
Röchling Engineering Plastics SE & Co. KG,Haren, Germany, offers Durostone UPM S13 LST and Polystone MK FL, two flame-retardant plastics which are now certified to the relevant requirements of the new European rail vehicle standard EN 45545-2:2013. Röchling thus expands its range of products and materials for the demanding industrial sector of railway engineering.
Durostone UPM S13 LST
Durostone UPM S13 LST is a glass-fiber-reinforced plastic consisting of unsaturated polyester resin reinforced with glass mat. The suffix LST stands for Low Smoke & Toxicity. Durostone UPM S13 LST is specially formulated to produce only a small amount of smoke and toxic gases in the event of a fire. The material thus makes it easier for designers to comply with the high safety requirements in railway engineering. Durostone UPM S13 LST meets requirement R11, hazard level HL3, for arc resistant insulation materials of EN 45545-2:2013.
With a high glass content and specially developed resin matrix, Durostone UPM S13 LST offers high strength both at room temperature and at higher temperatures. The density of 2.10 g/cm³ makes it possible to manufacture components that are lightweight but at the same time have high mechanical strength. Typical areas of application are mounts on bogies for current collectors (shoebeams), cover plates, snuffer boxes, switchgear, throttles and design elements for dry-type transformers. The material is supplied to customers in the form of pressed sheets, and as machined components and compression-molded parts according to customer drawings.
Polystone MK FL
In the area of thermoplastics, Röchling offers Polystone MK FL, a flame-retardant PE-UHMW which now meets the relevant requirements of the new European rail vehicle standard EN 45545-2:2013. With a very low density of 1.0 g/cm³, this material supports the lightweight construction of rail vehicles, whilst offering excellent slide properties and high abrasion resistance.
The properties of Polystone MK FL make it particularly suitable for components which have to meet high requirements in terms of slide properties and abrasion resistance. Examples of typical components are slide elements, cable clamps and linings.
Polystone MK FL is available in the form of pressed sheets and high-quality machined and extruded machined parts in accordance with customer drawings in small and large dimensions, with complex geometries and close tolerances.
