Abstract: Embodiments of the present disclosure are directed to articles comprising a crosslinked reaction product of ethyl-ene-based polymer, polyolefin; silane crosslinker; and 1 to 5 weight percent (wt %) of a metallic stearate catalyst. The ethylene-based polymer is silane grafted. The grafted silane enables at least one intramolecular silane crosslinking of the ethylene-based polymer and intermolecular silane crosslinking of the ethylene-based polymer and the polyolefin.

Abstract: A thermoplastic elastomer (TPE) compound is disclosed which has very low hardness by virtue of the use of a combination of high styrene content styrene-ethylene-ethylene-propylene-styrene copolymer, a conventional styrene-ethylene-ethylene-propylene-styrene copolymer, and a plasticizer. Super-soft extruded or molded plastic articles may be formed from pellets of the compound, with a resulting Shore OO Hardness of between about 35 to about 52. Molded articles may be prepared using injection molding techniques.

Abstract: An adhesive composition includes, based on a total weight of the adhesive composition, 18 wt % to 30 wt % of a styrene-ethylene/butylene-styrene triblock copolymer, 6 wt % to 30 wt % of a tackifier, 30 wt % to 50 wt % of a white mineral oil, and 5 wt % to 35 wt % of an incompatible polymer composition. The styrene-ethylene/butylene-styrene triblock copolymer has a weight average molecular weight of 90,000 g/mol to 140,000 g/mol. The tackifier has a weight average molecular weight of 500 g/mol to 5000 g/mol, a glass transition temperature of 50° C. to 100° C., and a softening temperature of 100° C. to 140° C. The incompatible polymer composition includes at least two of a high density polyethylene, a crosslinked ethylene-propylene-diene rubber, and an olefin block copolymer.

Abstract: Thermoplastic articles are molded from thermoplastic polyurethane compounds including blends of aliphatic poly-caprolactone thermoplastic polyurethane and aromatic thermoplastic polyurethane selected from aromatic polyester thermoplastic polyurethane, aromatic polyether thermoplastic polyurethane, and combinations thereof. The thermoplastic articles exhibit enhanced stain resistance, as represented by achieving a rating of 2 or better according to Blue Jean Abrasion Test, relative to thermoplastic articles molded from thermoplastic polyurethane compounds including either aromatic polyester thermoplastic polyurethane or aromatic polyether thermoplastic only, while also having good clarity (i.e., low haze) and other desirable properties. The thermoplastic articles can be especially useful as protective cases for handheld electronic devices.
