  • Patent number: 7485683
    Abstract: A compatibilizer including a first portion compatible with a fluoropolymer and a second portion compatible with a polyolefin. Compatibilized compositions comprising a polyolefin, a fluoropolymer, and a compatibilizer are also disclosed. Methods for forming both the compatibilizer and the blends contained in the compatibilizer are described. The compatibilized compositions of the present invention exhibit desired mechanical properties such as tensile strength and elongation. The flame retarded compatibilized blends exhibit desirable dielectric properties, are flame resistant and exhibit low smoke emission.

  • Patent number: 6977280
    Abstract: The use of polytetrafluoroethylene micropowders having a particle size of generally less than about 20 microns as an additive for polyvinyl chloride or polyolefin unexpectedly produces compositions which are melt processable. Other unexpected properties include that the micropowder is deformable under shear and acts as a flame retardant.

  • Publication number: 20050203230
    Abstract: Flame-retardant compositions of a polyvinyl chloride resin, a polyolefin, and a flame retardant are disclosed. The compositions are essentially free of plasticizers from the group consisting of: citrates; non-halogenated phthalates (e.g., di-2-ethyl-hexyl, di-n-octyl, dioctyl, diisooctyl, diisodecyl, dibutyl, dihexyl, or diheptylnonyl); bisphthalates; benzoates; trimellitates; pyromellitates; azelates; polymeric plasticizers based on adipic, azelaic, or sebacic acids and glycols such as ethylene, propylene, and butylene, with either alcohol or monobasic acid termination (e.g., benzoate diester of 2,2,4-trimethyl pentanediol or triethylene glycol di-2-ethylhexanoate); epoxies; esters of dibasic acids (e.g., aliphatic ester adipates such as dioctyl adipate, aliphatic ester sebacates such as dioctyl sebacate); alkyl sulfonate esters; aliphatic hydrocarbons; aromatic hydrocarbons; alkylated aromatic hydrocarbons; butyl phthalyl butyl glycollate; isobutyrate; dipentaerythritol esters; and combinations thereof.
