This is a High Performance Compressible Acoustic Insulation It fits a wide range of applications where varying thickness is highly desired, such as door trim panels and body side trim panels. The products are uniquely high performance and low density making them ideal for mass reduction applications. The web is composed of 50% polyester staple fibres, and 50% polypropylene fibres. The polypropylene fibres are extremely fine, producing the high-energy absorption characteristic with the low weight. The polyester fibres are added to strengthen the web. The scrim attached to both sides is a 100% polypropylene non-woven fabric. It is conformable to accommodate the irregular spaces behind trim panels, headliners and instrument panels. Fills voids to help reduce unwanted noise from travelling throughout the vehicle. It can be processed by conventional techniques such as die-cutting and heat sealing. Attaching to trim panels is easy with this product, using the attached self-adhesive backing. Not recommended for applications where temperatures will be above 120°C
