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 sat 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.

Process for producing foam article

The present disclosure provides a composition. The composition contains (A) an ethylene/α-olefin copolymer containing (i) ethylene and (ii) from 20 wt % to 35 wt % C-Cα-olefin comonomer, the ethylene/α-olefin copolymer having a density from 0.880 g/cc to 0.895 g/cc, a melt viscosity, at 177° C., from 4,000 mPa·s to 20,000 mPa·s, and a glass transition temperature from −55° C. to −20° C.; (B) a tackifier, and (C) a wax.

Adhesive composition

A process to make a friable bale, and a friable bale formed from the same, wherein the friable bale is formed from a composition comprising coated polymer particles, which comprise polymer particles formed from a polymer composition comprising an olefin-based polymer, and a coating formed from a coating composition comprising an aqueous metal acid dispersion, and an aqueous polysiloxane emulsion, and wherein the friable bale has a compression force ≤1.00 MPa.

Friable bales

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.

Foam bead and sintered foam structure

The present disclosure provides a foam bead. The foam bead contains at least one of the following components: (A) a block composite; and/or (B) a crystalline block composite. The present disclosure also provides a sintered foam structure formed from a composition comprising at least one of the following components: (A) a block composite; and/or (B) a crystalline block composite.

The present disclosure provides a foam bead. The foam bead is formed from a composition containing (A) a silane-functionalized ethylene/α-olefin multi-block interpolymer. The present disclosure also provides a sintered foam structure. The sintered foam structure is formed from foam beads that are formed from a composition containing (A) a silane-functionalized ethylene/α-olefin multi-block interpolymer.
