Rogers High Elastomer Materials for HEV Seals in Hybrid Electric Vehicles

HEV Seals

Hybrid electric vehicles (HEVs) utilize electricity and conventional fuel engine technology. Hybrid electric vehicles can have very small batteries because the batteries are only used occasionally. This controls the cost and total volume of the vehicle, but it also creates several problems, such as smaller access ports and smaller sealing ports for the battery pack to come into contact with the outside world. The battery gasket also prevents further leakage of battery fluid. In addition, HEV propulsion technology has greatly increased the number and complexity of electronic parts inside the vehicle. PORON polyurethane and BISCO silicone provide long-lasting support, aligning the cells, insulating them from dust and liquids, and preventing vibration-induced damage.

Environmentally Sealed

Like many vehicles, HEVs need to withstand all the elements and forces in the environment. Safety should be factored in as serious damage can occur, for example, battery packs can be electrocuted or explode if they are not well sealed.BISCO silicone gaskets seal the socket between the battery and the grid, are resistant to ultraviolet rays, and are also tough at low temperatures.PORON urethanes are an even more economical choice.

Vibration Isolation

Battery packs need to be able to absorb internal shock energy as well as provide vibration control within the pack, between packs, and to surrounding vehicles. the compression resistance (C-set) of BISCO silicone foams withstands collapse caused by long-term compressive stress and temperature changes, extending the life of the battery through constant sealing and shock absorption.

Battery shock pads

HEV battery packs use shock pads/springs to hold components securely in place and, if necessary, tightly between them.PORON polyurethane foam is characterized by a consistent rebound force over a range of compression conditions. This allows designers to predict the resilience behavior of the material even at varying tolerances.
