Abstract

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/C₃-C₁₀ alpha-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.
