Patents Assigned to Celanese EVA Performance Polymers Corporation
  • Polymer composition for use in cables
    Patent number: 10752760
    Abstract: A polymer composition that comprises an olefinic polymer, a flame retardant that includes a halogen-free mineral filler, and a compatibilizing agent is provided. The halogen-free mineral filler constitutes from about 20 wt. % to about 80 wt. % of the composition. The composition may exhibit a degree of water uptake of about 5 wt. % or less after being immersed in water for seven days at a temperature of 23° C.

  • Polymer composition for forming a melt-extruded film and composites thereof
    Patent number: 10155859
    Abstract: A polymer composition that can be used to form a melt-extruded film is provided. The polymer composition may contain an olefinic polymer and a transition metal salt. By selectively controlling specific aspects of the polymer and the transition metal salt, as well as the relative concentration of each component, the present inventors have discovered that the resulting composition can exhibit a relatively fast oxidation rate, which has been found to improve the adhesion of the composition to a wide variety of substrates.

  • Medical tube
    Patent number: 9896576
    Abstract: A medical tube that contains a polymer composition that is generally flexible and biocompatible is provided. The polymer composition contains at least one ethylene vinyl acetate polymer and at least one viscoelastic additive. By selectively controlling specific aspects of the ethylene vinyl acetate polymer (e.g., vinyl acetate content, melt flow index, density, etc.), the viscoelastic additive, and the manner in which they are blended, the resulting composition can exhibit a reduced tendency to kink when formed into the medical tube.
