3M™ Thinsulate™ is a unique non-woven acoustic absorber composed of polyester and polypropylene fibers. The polypropylene fibers are extremely fine, producing a high-energy absorption characteristic with low weight. The polyester fibers are added to strengthen the web, while the scrim protects and contains the fibers. The fine microfibers absorb high frequency noise, and the thicker fibers provide recovery and loft. It is compressible, lightweight, and conformable.
