Abstract
The present disclosure provides an article. The article includes a crosslinked foam composition, an adhesive layer, and a substrate composed of an olefin-based polymer. The crosslinked foam composition includes an ethylene/α-olefin multi-block copolymer, an ethylene/propylene/diene terpolymer (EPDM), optional silicone rubber, optional blend component selected from ethylene/α-olefin random copolymer, ethylene-vinyl acetate copolymer (EVA), styrene-butadiene block copolymer, hydrogenated styrene-butadiene block copolymer, and combinations thereof, optional plasticizer, optional filler, and optional additive.
