Commuters in major metro areas choose trains as their mode of transportation because trains allow them to enjoy a safe, comfortable ride and avoid driving through rain or snow. When train cars lose power, though, it causes delays for the affected train and others caught behind it on the track. Even worse, trains without electrical power lose their ability to regulate the internal temperature of the cars. During the summer, temperatures inside the car can reach 38° C (100° F) if not cooled. In the winter, lost power can result in passengers facing below freezing temperatures inside the cars.

rail_app_noteA commuter train operator was facing this challenge on a regular basis because their electrical panel, located on the external surface of the car, was failing. The extruded rubber gasket that filled the space between the electrical panel and the car was not holding up to the harsh weather conditions. It hardened over time, producing gaps where wind, rain, and sun damaged the electrical panel. The result was loss of power.

Rogers’ BISCO® BF-1005 extra soft silicone foam material provided the right solution.

The compression set resistance of the BF-1005 silicone material made it the right material to fill the spaces created by the inadequate seal of the extruded rubber gasket. In addition, the softness of BF-1005 silicone material allowed it to easily fill the difficult geometries needed to maintain a good seal and keep the elements from shorting out the electrical panel. What’s more, the commuter train operator did not need to waste man-hours removing the old, dried out rubber gasket before installing the BF-1005 silicone foam. A Rogers Preferred Converter provided a precut peel and stick ready-to-use solution, which saved the customer time and money on installation. BF-1005 silicone foam meets ASTM E162, ASTM E662 and SMP 800C standards for flame, smoke, and toxicity requirements on trains.

Rogers’ BISCO® product family offers a wide range of multi-functional silicone-based elastomeric foam and solid materials for use in rail interior applications such as seals, gaskets, floor isolation pads, thermal insulation, sound barriers and anti-squeak / rattle pads. These materials are offered in continuous sheet form, enabling ease of fabrication whether slitting, die-cutting, or laminating with adhesive. In addition, Rogers offers a highly durable silicone seat cushion foam, supplied in bun stock form or as a fabricated cushion shaped to the customer’s design requirements.

innotrans_logoOur high temperature BISCO® silicone materials for rail will be on display at InnoTrans 2016, the place to be for anything and everything rail and public transportation: railway technology, infrastructure, public transport, interiors, and tunnel construction.

InnoTrans 2016
September 20-23, 2016
Messe Berlin
Hall 3.1 / 513

At the show, we’ll be featuring the BISCO MF1® 35 (35 IFD) and MF1® 55 (55 IFD), high quality silicone foam materials designed for seat cushion applications. They feature exceptional flame, smoke, toxicity (FST) characteristics, superior weather and UV-resistance, and low compression set to ensure safety, long-term comfort, and durability. They are available in slab form or may be fabricated to customer specifications.

Engineers and designers can quickly find the material that’s right for their application by downloading the BISCO Silicones Rail Interior Solutions Application and Material Guide.
