  • Elastomeric composition having oil resistance
    Patent number: 9422428
    Abstract: An oil resistant polymer composition is disclosed that contains a thermoplastic elastomer combined with an olefin and vinyl acetate copolymer on an oleophobic agent. In one embodiment, the composition contains a thermoplastic polyester elastomer combined with an ethylene and vinyl acetate copolymer. In order to render the polymer composition oil resistant, the polymer composition can further contain an UHMW silicone, a fluoropolymer, and optionally a crosslinking agent and/or an antiplasticizer.
    Type: Grant

  • COPOLYESTER ELASTOMER AND AN ALPHA-OLEFIN VINYL ACETATE COPOLYMER HAVING FLAME RETARDANT PROPERTIES
    Publication number: 20150218365
    Abstract: A flame resistant polymer composition is disclosed that contains a thermoplastic elastomer combined with an ?-olefin and vinyl acetate copolymer. In one embodiment, the composition contains a thermoplastic polyester elastomer combined with an ethylene and vinyl acetate copolymer. In order to render the polymer composition flame resistant, the polymer composition contains one or more non-halogen flame retardants. The flame retardants may comprise phosphinates, polyphosphates, and/or melamine cyanurate. The polymer composition also contains a char promoter, an anti-dripping agent, or both.
