Application of silicone foam in noise reduction in automobile and industry

Sound insulation and silencer materials need to choose porous materials, in order to "capture" sound intensity wave energy, the kinetic energy will be in the hole back and forth, the final loss of mechanical kinetic energy and can not be infiltrated out. Silicone foam can provide sound insulation and noise reduction for passengers to show reliable noise isolation and vibration reduction solutions. Silicone foam itself has a polyurethane elastomer with high resilience, which is very suitable for sound insulation and noise reduction. It has extraordinary anti-peristalsis, anti-compression and deformation ability, excellent resilience, sound insulation and shock absorbance and impact digestion and absorption performance.

Reducing noise, vibration and unsteadiness such as beeping, squeaking and rattling is the basic rule to improve the driving experience of vehicle customers. With the BSR project, the vibration of the sound transmission based on the reduction structure and the gas transmission of the sound from the road to the cabin based on the wood floor can be significantly reduced. Silicone foam can reduce BSR and improve NVH characteristics. Silicone foam recipe is different, not easy to shrink deformation or collapse, can show reasonable sealing performance within the application period. This foam material is generally used as vibration cushion and aseismatic device, with high elastic force, excellent shock absorption and impact digestion and absorption properties.

Silicone foam products are committed to the design of low frequency vibration reduction in harsh natural environment, is the development and design of the thicker, the most solid, the most powerful, the most durable silicone foam products. The design team found that the product can reliably handle noise, vibration and instability in demanding natural environments such as industrial production machinery, crude oil/gas, electricity generation and transportation.
