摘要： A foam bead is formed from a composition comprising an ionomer comprising, in polymerized form, ethylene, an unsaturated acid comonomer and, optionally, an acrylate comonomer, wherein the unsaturated acid comonomer is at least partially neutralized with a neutralizing agent. A sintered foam structure is formed from foam beads that are formed from above composition.

摘要： The present disclosure provides a fabric laminate. In an embodiment, the fabric laminate includes a fabric sheet, a coating layer, and a tie layer. The fabric sheet is composed of propylene-based polymer fibers. The coating layer is composed of one or more ethylene-based polymers. The tie layer is located between the fabric sheet and the coating layer. The tie layer is composed of at least 50 wt % of a crystalline block composite (CBC) and an optional blend component. The CBC includes (i) an isotactic crystalline propylene homopolymer (iPP); (ii) an ethylene/propylene copolymer; and (iii) a diblock with the formula (EP)-(iPP). The CBC has a block composite index (CBCI) from 0.1 to 1.0. The fabric laminate has a peel force from 20 N/15 mm to 40 N/15 mm.

摘要： The present disclosure provides a process. In an embodiment, the process includes providing a foamable composition. The foamable composition includes an ethylene-based elastomer, a blowing agent, and a peroxide. The process includes heating the foamable composition to form a pliable formulation. The pliable formulation has (i) a viscosity (0.1 rad/s at 180° C.) from greater than 70,000 Pa·s to 2,000,000 Pa·s, (ii) a tan delta (0.1 rad/s at 180° C.) from 0.2 to less than 2, (iii) a strain hardening index greater than 2.5 to 6, and (iv) an extensional viscosity (1 s−1 at 180° C.) from greater than 400,000 Pa-s to 7,000,000 Pa-s. The process includes introducing the pliable formulation into a mold having an expandable mold cavity and unidirectionally expanding the expandable mold to form a crosslinked foam article. The process includes cooling, in the expanded mold, the crosslinked foam article; and removing the crosslinked foam article from the expandable mold.
