Provided are compositions comprising: (a) an ethylene-propylene-diene terpolymer having a Mooney viscosity [ML(1+4) 125&#xb0; C.] of about 25 to about 300 and an ethylene content of at least about 60 wt % of the ethylene-propylene-diene terpolymer; and (b) a polyolefin elastomer. The presence of the polyolefin elastomer improves rheological properties of the composition to an extent that does not significantly compromise other properties, such as tensile strength at break and compression set.

Compositions comprising EPDM and a polyolefin elastomer, preparation and use thereof

This disclosure relates to a polymer composition comprising (A) a first polymer; (B) one or more fillers; and optionally (C) a cross-linking pack including cross-linking agents and coagents. The first polymer comprises at least one of (i) a propylene-based copolymer and (ii) an ethylene/C-Calpha-olefin copolymer. The one or more fillers comprise at least one of carbon black, ferrite magnet powder, calcium carbonate, alumina trihydrate, magnesium hydroxide, talc, titanium dioxide, fibers, marble dust, cement dust, clay, feldspar, silica or glass, fumed silica, alumina, magnesium oxide, antimony oxide, zinc oxide, barium sulfate, calcium sulfate, aluminum silicate, calcium silicate, titanium dioxide, titanates, clay, nanoclay, organo-modified clay or nanoclay, glass microspheres, chalk, or any combination thereof. The cross-linking agents comprise organic peroxide, and the coagents comprise at least one of di- and tri-allyl cyanurates and isocyanurates, liquid and metallic multifunctional acrylates and methacrylates, zinc-based dimethacrylates and diacrylates, and functionalized polybutadiene resins.

High filler loaded polymer composition

A closed cell foam material contains a propylene based polymer comprising from about 5% to about 32% by weight &#x3b1;-olefin units. The propylene based polymer has a heat of fusion, as determined by DSC, of less than 80 J/g. The material also contains 0.5 to 5 phr peroxide, 1.0 to 5.0 phr blowing agent, and 0.1 to 10 phr co-agent. The cells of closed cell foam material have a diameter in the range of 0.1 to 1.5 mm.
