Rail engineering is constantly evolving. Currently under construction, the new HS2 railway has already been called “the most sustainable high-speed railway in the world”, thanks in part to its implementation of low carbon concrete.

In other rail news, the newly dubbed “Internet of Trains” blends engineering with technology – in seat sensors and real-time schedule updates, for example. These developments are exciting, but when we strip the industry back to basics, which material is being increasingly used as technology advances?

The answer, of course, is silicone.

Where do you find silicone rubber in rail engineering?

In rail engineering, you can find silicone in both interior and exterior applications:

·                  Wall and ceiling insulation

·                  HVAC seals and gaskets

·                  Exterior light seals

·                  Vibration dampening

·                  LED display seals

·                  Interior door seals

·                  Seat cushioning

·                  Electrical enclosure gaskets

What are the benefits of silicone?

There are a vast range of benefits for using silicone in rail engineering, which depend on the product you opt for. Here are just some of the advantages gained when using silicone for rail projects:

·                  Flame retardant

·                  Low smoke toxicity

·                  Extreme temperature resistance (-60°C to 270°C)

·                  High tear strength

·                  Improved abrasion resistance

·                  Excellent durability and lifespa
