FLAME RETARDANT CROSSLINKABLE POLYMERIC COMPOSITIONS

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 or a polymeric processing additive. 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.
