  • Plastics for railway engineering and rail vehicles

    Rail transport takes people and goods safely and rapidly from A to B. Once on rail, reliable and powerful technology is required. Every designer is faced with the challenge of developing fast, safe and cost-efficient rail vehicles. Our plastics help you with this task: depending on the material, they are very light, for instance, yet mechanically stable and compliant with standards such as DIN EN 45545-2:2013. That reduces the weight of your rail vehicles while at the same time improving economy and safety.

    Your advantages

    Typical areas of application

    Product examples

    External and internal cladding

    With their low weight, high strength and flame retardant properties, our non-conductive Durostone® glass fibre-reinforced profiles are used for external and internal claddings in rail vehicles around the world. More information about Durostone® profiles

    Cable clamps made of flame-retardant PA 6

    Our material SUSTAMID 6 FR (PA6) meets the relevant requirements of rail vehicle standard DIN EN 45545-2:2013. As an extruded semi-finished product, it allows finished parts of large dimensions to be manufactured in small quantities – such as cable clamps for rail vehicles (image).

    Flame retardant components made of Polystone® MK FL according to EN 45545-2

    Customized machined flame-resistant components made of Polystone® MK FL contribute to the safety, lightweight construction and efficiency of rail vehicles. The material fulfills the relevant requirements of the European rail vehicle standard EN 45545-2: 2013 and at the same time offers very good sliding properties as well as a low density of only 1 g/cm³. We will be pleased to machine components for your application according to your specifications with complex geometries and tight tolerances. With our state-of-the-art machinery, we are specialized in the machining of high-quality parts according to customer's requirements. Typical components for railway technology are sliding elements, cable clamps, linings and other components.

    Insulating parts for rail transformers

    The energy supply of locomotives is vitally important. We offer fully assembled components made of Lignostone® Transformerwood® for locomotive transformers. They offer excellent insulating properties alongside very high mechanical strength and have been used successfully in mineral oils and synthetic esters such as Midel® 7131 for decades.

    Wagon linings

    The use of freight wagons for a wide variety of bulk goods demands a balance between protecting against wear and minimizing friction. For hopper, saddle or standard type wagons we recommend using our Matrox® material. Matrox® combines the best surface friction with the highest abrasion resistance, enhancing the optimum material flow of your bulk goods. More information about Matrox®

    Insulated cover for current collector

    Durostone® UPM S13 LST is a glass-fibre reinforced plastic consisting of unsaturated polyester resin reinforced with glass mat. The material meets the requirement R11, hazard level HL3, for arc resistant insulation materials of EN 45545-2:2013. 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 applications are mounts on bogies for current collectors (shoebeams), cover plates, snuffer boxes, switchgear, throttles and design elements for dry-type transformers.

    Slide elements made of Polystone® MK FL

    With Polystone® MK FL we offer a flame-retardant PE-UHMW which meets the relevant requirements of the 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 make it particularly suitable for components which have to meet high requirements in terms of slide properties and abrasion resistance like slide elements.

    How to find the right plastics for fire protection?

    Fire protection is essential in railway technology. However, blanket demands for materials that meet the highest hazard level in EN 45545 are not very productive. This limits the choice of materials unnecessarily and may not make economic sense. For this reason, the material must be selected individually for each requirement. But which plastics are suitable for which applications? Read more about the selection of flame retardant materials for railway technology.
