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&#xb0; C. and a melting temperature of at least about 115&#xb0; 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&#xb0; 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/m.

Crosslinked polyolefin foam sheet with exceptional softness, haptics, moldability, thermal stability and shear strength

A crosslinked, closed cell polyolefin foam sheet has exceptional softness, haptics, moldability, thermal stability and shear strength as well as a laminate and uses thereof.

A flooring system having a top floor layer, a sub-floor, and an underlayment material disposed between the sub-floor and the top floor layer is disclosed. The underlayment material may include a cross-linked, polyolefin foam having a moisture vapor transmission rate of less than about 3.0 lb/1000 ft/24 hr, and an average sound pressure level of less than about 15 dB over a range of about 300 Hz to about 1000 Hz. The foam may have a compressive strength of at least about 0.85 kg/cm. Foam density, gel fraction, and resin blend may combine to provide an underlayment material having such reflective sound and moisture vapor barrier properties.
