PORON® Material Improves Passenger Comfort


Rogers PORON® 4701-40 Effectively Reduces Noise and Vibration

The Challenge

Noise and vibration are generated when a vehicle’s fuel pump is in operation and when the fuel tank and under body components come in contact. This airborne and structural noise travels to the interior of the vehicle causing passenger discomfort. In an effort to reduce the noise and improve the passenger’s experience, isolator pads are placed in strategic contact areas around the fuel tank.

The isolator pads must reduce the noise generated by the fuel pump and isolate vibration caused by component contact.
