Abstract: A method of making a foam composition includes blending a composition including (i) about 15 to about 75 parts by weight of an olefin block copolymer with a controlled block sequence having a melt flow index of about 0.1 to about 15 grams per 10 minutes at 190° C. and a melting temperature of at least about 115° C., (ii) about 25 to about 85 parts by weight of at least one polypropylene based polymer having a melt flow index from about 0.1 to about 25 grams per 10 minutes at 230° C., (iii) a crosslinking monomer and (iv) a chemical blowing agent to produce a blended composition; crosslinking the blended composition to obtain a crosslinked composition having a crosslinking degree of about 20 to about 75%; and foaming the crosslinked composition at an elevated temperature to obtain a foam composition having a density of about 20 to about 250 kg/m3.

Abstract: A pipe lagging system for acoustically insulating a drain piping system includes at least one drain pipe and drain pipe connector coupled to the drain pipe. The pipe lagging system includes at least one preformed acoustic lagging sleeve adapted to be put over the drain pipe of the piping system for acoustical insulation, at least one preformed acoustic clamshell jacket adapted to fit over the drain pipe connector of the piping system for acoustically insulating the pipe connector. The clamshell jacket is adapted to receive an end portion of the tubular sleeve put over the drain pipe. At least one mechanical fastener is adapted to mechanically secure the clamshell jacket and the received tubular sleeve to the underlying drain pipe. At least one of the at least one tubular sleeve and clamshell jacket includes a sound-insulating foam material.
