摘要： Embodiments of the present disclosure are directed to thermoset articles including a crosslinked reaction product of thermoplastic polyolefin, at least one of ethylene alpha-olefin polyolefin elastomer and ethylene propylene diene rubber, nitrile butadiene rubber, and silane. At least one of the thermoplastic polyolefin, the at least one of the ethylene alpha-olefin polyolefin elastomer and the ethylene propylene diene rubber, and the nitrile butadiene rubber is silane grafted and silane crosslinked. The silane crosslinking is at least one of intramolecular silane crosslinking and intermolecular silane crosslinking.

摘要： 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.

摘要： Disclosed is a process for creating an elastic film or sheet by calendaring a composition, including a polymer and a fabric. The composition may include a polymer, a cotton, or a combination of both. The calendared composition can form tough, flexible films and sheets. The film and sheet can have optical and physical properties that make them suitable as a replacement for some PVC films. Also disclosed is a composition for calendaring including a fabric and a polymer.

摘要： Thermoplastic articles are molded from thermoplastic polyurethane compounds including aromatic polycaprolactone thermoplastic polyurethane. The thermoplastic articles exhibit enhanced stain resistance, as represented by achieving a rating of 1 according to Blue Jean Abrasion Test, relative to thermoplastic articles molded from thermoplastic polyurethane compounds including other types of thermoplastic polyurethanes, 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.
