Abstract:
A hybrid underlayment, includes a thermoplastic making up between 92.0% by volume to 95.5% by volume of the hybrid underlayment. A plurality of expanded microspheres is dispersed through the thermoplastic. The microspheres are expanded to a volume in a range of between 180 square micrometers and 1450 square micrometers. The microspheres makeup between 1.0% by volume to 7.5% by volume of the hybrid underlayment. The hybrid underlayment is extruded into a flat sheet having a thickness of between 1.0 mm and 2.0 mm and a density from 7 pcf to 25 pcf.
