Specialty silicone and urethane foams with excellent memory for long term solutions to reduce vibration-induced noise in interiors often known as Noise Vibration and Harshness. Most noise from vibration occurs because of friction or impact. Other factors include temperature, humidity, product age and load environment. Poron® microcellular urethanes and Bisco® Silicone foams exhibit excellent resistance to collapse, good vibration damping, sound dampening and impact absorption. These features serve to extend the life of products by continuing to seal and dampen vibration throughout the life of the product.
