  5. Very Light Weight for Mass Reduction  Part of our TC family of cavity filling solutions for automotive OEM, 3M™ Thinsulate™ Acoustic Insulation TC1803 has one of the highest acoustic absorption-to-weight ratios of any Thinsulate product. This very low density (8.8 kg/m3) insulation is excellent as an NVH cavity filler for applications where mass reduction is a major goal. Its internal web features thick and thin fibers and is designed specifically to absorb vibration and help reduce unwanted noise from traveling throughout vehicles. Built for Lasting Noise Absorption The internal web of the product is composed of a combination of polyester (PE) and polypropylene (PP) fibers. The PP fibers are extremely fine, allowing for high-energy absorption without adding weight. The thicker PE fibers add loft, strength and stability to the web. The lightweight reinforcing white scrim on both sides is made from 100% polypropylene non-woven fabric for durability. Properties of 3M™ Thinsulate™ Acoustic Insulation TC1803 This acoustic insulation material has a caliper of 21 mm and a basis weight of just 185 g/m2. Fibers are contained in a single scrim. Compressible and Conformable for Gap Filling Thinsulate Acoustic Insulation TC1803 is designed for excellent compressibility and recovery. This is ideal for applications where filling spaces of varying thickness is important, such as door trim panels and body side trim panels. As the insulation conforms, it completely fills even irregular spaces for extremely consistent noise absorption throughout the application. It is most effective as an NVH cavity filler. Our Thinsulate Acoustic Insulation TC1803 can be processed by conventional techniques such as die cutting. It attaches easily using ultrasonic welding, hot melt adhesive or mechanical fasteners. Recommended Applications:  Variable cavity NVH Door trim panel Door hole seals Head liners Wheel wells Trunk liners
