Buzz, Squeak, Rattle / Noise, Vibration, Harshness

Vibration between mating components can lead to objectionable sounds that reduce the perceived quality of a product. Hybrid Electric Vehicles, for instance, have significantly quieter engines. This means the noise being generated by poor door seals or vibrating parts is no longer masked. PORON® Urethane Foams reduce BSR (buzz, squeak, and rattle) and provide improved NVH (noise, vibration, and harshness) characteristics. Their unique formulation will not take a set or relax, maintaining an effective seal over the life of the material.

Vibration Isolation

Most noise caused from vibration occurs because of friction or impact. Temperature, humidity, product age, and load environment impact the amount of BSR. PORON® Urethane Foams provide excellent resistance to compression set (collapse), and exhibit high resiliency, good vibration damping, and impact absorption. This extends the life of the product by continuing to seal and absorbing shock.

Wide Range of Materials

PORON® Urethane Foams are available in a range of firmnesses and thicknesses for a wide variety of applications, from soft materials for automotive fuel tank isolator pads and camera window gaskets to very firm foams for enclosure gaskets. PORON materials are inherently flame retardant; many meet flammability requirements of UL HBF and MVSS 302.
