J-Flex offers an extensive range of unique elastomer materials for Surface, Sub-Surface, Tunnel and Rolling Stock applications

J-Flex EPDM, Silicone and Neoprene and Vamac® materials are tested and approved to EN45545-2 and many other certifications, including LUL S1085 compliance and are designed specifically for low smoke low toxicity requirements, particularly with regards to enclosed space applications.

This makes them ideal for all safety critical applications in rail, mass transit, marine vessels, oil & gas, public transport and heavy goods vehicles. With resistance to corrosion, moisture, salt and light fuels, they offer outstanding flexibility, strength and durability. This includes environmental resistance – withstanding Ozone, U.V., rain and frost – meaning outdoor applications such as lighting systems and enclosures are kept water and dust tight.

Vamac® for example has excellent abrasion resistance, so is ideal where wear is a concern – one notable use being protection of cables laying on ballast trackside. Gaskets and seals for enclosures such as lighting fixtures, battery boxes/ covers and the like will prevent the ingress of environmental factors.

Extruded seals are perfect for glazing partitions, door portals and floor covings. Anti-vibration gaskets and mouldings come into play for seating mounts and floor vibration dampening. As you can imagine, our various elastomers can perform many functional and critical roles within Surface, Sub-Surface, Tunnel and Rolling Stock applications. With various degrees of hardnesses being available, and gaskets, seals and mouldings being achievable in virtually any required dimensions, the possibilities are endless.
