    摘要: The invention relates to improved flame retardant crosslinkable compositions useful as insulation coatings for wire and cable based on ethylene-vinyl ester and ethylene-alkyl acrylate copolymers. The compositions contain a hydrated inorganic filler, an alkoxysilane, an antioxidant and a hydrocarbon processing oil. Organic peroxides are preferably employed to facilitate crosslinking. A method for providing the improved flame retardant crosslinkable compositions and electrical conductors coated therewith are also provided.

    摘要: The present invention relates to improved flame retardant insulation/jacketing compositions for wire and cable products based on ethylene-vinyl ester and ethylene-alkyl acrylate copolymers. The copolymers are formulated with a hydrated inorganic filler, an alkoxysilane, a crosslinking agent, a processing additive and a combination of specific antioxidants, namely, a pentaerythritol betaalkylthiopropionate and a hindered phenol. The formulations stabilized with the pentaerythritol betaalkylthiopropionate/hindered phenol combination have good heat stability and do not tarnish or discolor the surface of the copper conductor upon steam vulcanization.

    摘要: Flame retardant and abrasion resistant crosslinkable compositions useful as insulation for wire and cable are provided. The compositions contain an ethylene-vinyl acetate copolymer having a vinyl ester content of 5 to 12 wt. %, a halogenated compound, antimony trioxide and an organic peroxide. Use of specific halogenated compounds, particularly brominated aromatic compounds, with low vinyl acetate content ethylene-vinyl acetate copolymers yield products which are highly resistant to abrasion after crosslinking.
