  • Patent number: 11753534
    Abstract: Compositions comprising post-consumer recycled (PCR) waste are described. The PCR is combined with at least one virgin resin and a propylene-based compatibilizer that enhances the blend between the PCR and virgin resin as well as improving one or more physical properties of the composition. The propylene-based compatibilizer is a reactor made thermoplastic polyolefin or a heterophasic copolymer with a semi-crystalline matrix and a rubber component. This allows for the selection of a compatibilizer that can shift the composition's physical properties based on the end use application, and provide a stronger, miscible blend.

  • Patent number: 8207248
    Abstract: Disclosed is a colored high density polyethylene composition. The composition comprises a high density polyethylene, phthalocyanine blue, and talc. The composition exhibits reduced warpage in molded articles compared to those which do not contain talc. The composition is useful for injection molding and many other applications where a blue color is needed and low warpage is desired.

  • Publication number: 20110244233
    Abstract: Disclosed is a radiation-curable insulation composition. The composition comprises from 5% to 35%, by weight, of an ethylene-vinyl acetate copolymer, 30% to 65% of a high density polyethylene, 30% to 60% of a metal hydroxide, 0.5% to 5% of a mercaptobenzimidazole salt, 0.05% to 5% of a phenolic antioxidant, 0.05% to 5% of zinc oxide, and 0.5% to 5% of a crosslinking agent. The composition is useful for wire and cable insulation applications. It provides the wire and cable insulation with improved abrasion resistance.

  • Patent number: 6083434
    Abstract: Improved compositions useful for the production of rotomolded articles having a foamed interior and non-foamed exterior skin are provided. The compositions of the invention are comprised of a first thermoplastic resin component which is an ethylene polymer in pellet form containing a chemical foaming agent, an organic peroxide and, optionally, a metal-containing activator compound and a second resin component which is a powder and can be a thermoplastic ethylene polymer or ethylene copolymer having less than 30% crystallinity. An improved one-step process for producing foamed rotomolded articles having foamed interiors and non-foamed exterior skins is also provided.

  • Patent number: 5830392
    Abstract: Improved compositions useful for the production of foamed rotomolded articles are provided. The compositions of the invention are comprised of a first thermoplastic resin component which is an ethylene polymer in pellet form containing a foaming agent and a second thermoplastic resin component which is a powder consisting of a mixture of different particle size and melt index ethylene polymers. An improved process for producing foamed rotomolded articles having uniformly foamed interiors and smooth exterior skins which are substantially free of surface defects is also provided.
