Abstract: A shoe midsole composed of a foamed peroxide-crosslinked polyolefin elastomer includes a silane-grafted polyolefin component, an elastomeric component, and additives dispersed in the foamed peroxide-crosslinked polyolefin elastomer. The elastomer component includes one or more elastomeric polymers selected from the group consisting of ethylene vinyl acetate copolymer, polyolefin elastomers, olefin block copolymer, polyoctenamer, anhydride modified ethylene copolymers, ethylene propylene diene terpolymer, and combinations thereof. The silane-grafted polyolefin component and elastomer component are crosslinked with C—C bonds. Advantageously, the foamed peroxide-crosslinked polyolefin elastomer is substantially free of silane crosslinking as formed and substantially free of water. Characteristically, the additives and one or more elastomeric polymers are in sufficient amount that a melting temperature of crystalline regions in the foamed peroxide-crosslinked polyolefin elastomer is greater than 100° C. as measured by differential scanning calorimeter thermographs.

Abstract: A shoe midsole composed of a foamed peroxide-crosslinked polyolefin elastomer includes a silane-grafted polyolefin component and an elastomer component. The elastomer component includes ethylene vinyl acetate copolymer and a component selected from the group consisting of polyolefin elastomers, anhydride modified ethylene copolymers, and combinations thereof. The silane-grafted polyolefin component is crosslinked to the elastomer component with C-C bonds. The foamed peroxide-crosslinked polyolefin elastomer includes a plurality of closed cells. Characteristically, the foamed peroxide-crosslinked polyolefin elastomer is substantially free of silane crosslinking as formed and substantially free of water.

Abstract: A roofing accessory is disclosed includes an elastomeric layer including non-crosslinked elastomeric material having a composition including: (A) 100 PHR of a base polymer including ethylene propylene diene monomer (EPDM) having a sum of ethylidene norbornene (ENB) content, vinyl norbornene (VNB) content, norbornadiene content, and 1,4 hexadiene content and/or dicyclopentadiene (DCPD) content from about 0 to 9 wt. %, (B) about 50 to 300 PHR of calcium carbonate; and (C) about 50 to 200 PHR of a dewaxed heavy paraffinic process oil(s). The accessory may further include a butyl-based layer adjacent to the elastomeric layer. The accessory may also include a protective layer configured as a liner, the protective layer arranged adjacent to the butyl-based layer such that the butyl-based layer is sandwiched between the first and protective layers. The accessory may have elongation at break of up to about 1800%.

Abstract: A tread additive composition to be combined with a base composition for tire treads to achieve low rolling resistance includes an elastomeric component, a first additive component, and a second additive component. The elastomeric component includes a first silane-grafted polyolefine elastomer. The first additive component including a polymer carrier, a reinforcing filler, silane-terminated liquid polybutadienes, and one or more process activators. The second additive component including a butadiene rubber, a hydrocarbon resin, sulfur; and one or more accelerators. Advantageously, the tread additive composition can decrease rolling resistance and improve fuel economy when combined with a base tread composition as compared to treads formed from the base tread composition without the tread additive composition.
