  • Antistatic polyolefin foams and films and method of making the foam and antistatic composition
    Patent number: 5110841
    Abstract: Polyolefin foams and films having improved electrostatic properties are provided by incorporating into the polyolefin foam or film a novel antistatic additive composition comprising 0.1 to 10 parts per hundred based on the weight of the olefin polymer of a quaternary ammonium salt and 0.1 to 10 parts per hundred based on the weight of the olefin polymer of a partial ester of a long-chain fatty acid with a polyol. A method of making the foam containing the novel antistatic additive composition is also disclosed.
    Type: Grant
    Filed: September 16, 1991
    Date of Patent: May 5, 1992
    Assignee: The Dow Chemical Company
    Inventor: Bruce A. Malone
  • Fragrant thermoplastic foam and method of making the same
    Patent number: 5109029
    Abstract: Substantially closed-cell thermoplastic foams having a fragrance incorporated into the foam during extrusion are found to provide fragrant and long lasting release characteristics provided the foam is at least 70 percent closed cells. Generally the amount of fragrance is about 0.001 to about 5 weight percent of the total thermoplastic foam weight.

  • Coalesced polyolefin foam having exceptional cushioning properties
    Patent number: 4824720
    Abstract: Improved closed cell foams particularly suitable for use in packaging applications comprising a plurality of coalesced strands or profiles of a foamed thermoplastic composition.
    Type: Grant

  • Highly loaded coalesced foam
    Patent number: 4801484
    Abstract: Highly loaded improved closed cell foams comprising a plurality of coalesced strands or profiles of an alkenyl aromatic thermoplastic synthetic resin or mixture of an olefin polymer resin and a copolymer of ethylene with one or more copolymerizable comonomers having a lower melting point than the olefin polymer resin. The loading of the nucleating additive is in a range of about 0.5 to about 50 weight percent, based on total resin weight. When highly loaded with carbon black these foams are electroconductive foams.
