Hybrid Electric Vehicles (HEVs) draw on the strength of both electric and conventional fuel engines, enabling the battery to be smaller as it is used intermittently. This keeps vehicle cost and weight manageable, but presents challenges such as smaller maintenance openings, smaller seals for communication points and cylindrical cell washers with seals that can be an escape route for outbursts of battery chemistry. PORON® Polyurethanes and BISCO® Silicones are designed to reliably hold a consistent force, keeping battery cells aligned, sealed from dust and fluid, and isolated from the damaging effects of vibration.
BISCO® Silicones provide exceptional UV resistance and cold temperature flexibility. PORON® Polyurethanes offer an economical alternative.
BISCO® Silicone foam’s Compression Set Resistance (C-set) withstands collapse caused by the stresses of compression and temperature over time. This extends the life of the battery by continuing to seal and absorb shock.
PORON® Polyurethane foams have a unique ability to produce a very consistent level of force across a range of compressions. This allows the designer to predict the material’s behavior across varied dimensional tolerances.
