How Basotect Foam Reduces Engine Noise

Motorists have a great deal of sounds they have to listen for and pay attention to while driving - sirens, pedestrians, other vehicles and even the radio. Their engine should not be one of them.

Basotect has certainly earned itself a strong reputation for acoustic insulation, but the product has excellent thermal insulation properties as well.

Helping to meet the customer desire for a quieter vehicle is Basotect® melamine foam.  Basotect is a flexible, open-cell foam made from melamine resin, a thermoset polymer. The feature characteristic is its three-dimensional network structure.

"The product's unique properties make it an indispensable solution in multiple applications and industries," says Holli Woodard, market development specialist at BASF. "In the automotive industry, the acoustic properties of Basotect parts provide a drastic reduction of noise levels within a vehicle. With the ever tightening emission and CAFE standards engines are progressively running hotter.  Basotect's high heat resistance properties make it an ideal material for multiple powertrain applications.  It is also a lightweight option, which we know automakers are looking for."

Basotect foam's fine open cell structure is especially good at absorbing medium and high-frequency sound waves. It's also effective at absorbing low-frequency sounds when coupled with fleece or plastic covers, making it a good engine noise insulation solution.

Basotect has certainly earned itself a strong reputation for acoustic insulation, but the product has excellent thermal insulation properties as well. For that reason, many automotive manufacturers are using it as a heat shield solution in their vehicles.

In addition to its high sound-absorption capacity and thermal insulation properties, Basotect is also sought out for its flame-retardant characteristics, high-temperature resistance and low weight.

Basotect can be used in the following vehicle components:

  • Engine cover
  • Hood liner
  • Transmission tunnel
  • Firewall

This insulating foam not only enhances road safety, it also provides increased passenger comfort... a luxury drivers deserve and have come to expect.
