Zero halogen polyolefin compositions exhibit low smoke emission, low corrosivity, low toxicity, and low heat release properties, as well as flame resistance and char formation, while simultaneously maintaining favorable electrical insulation properties. Such compositions are especially useful for coating wires and conductors employed in high-speed speed telecommunication data transmission cables.

Low smoke emission, low corrosivity, low toxicity, low heat release, flame retardant, zero halogen polymeric compositions

A non-dripping, flame retardant, fluoropolymeric insulative composition comprises: (a) a fluoropolymeric base polymer; and (b) a nanoclay additive. The preferred nanoclay additive is selected from the group consisting of synthetic silicate montmorillonites, natural layered silicate montmorillonites and a layered alumna-silicate. Such compositions are especially useful for coating wires and conductors employed in high-speed speed telecommunication data transmission cables. A method for preparing an exfoliated thermoplastic elastomer blend of a fluoropolymer and a nanocomposite comprising dynamically mixing said fluoropolymer and said nanocomposite in a ratio of from about 99:1 to about 50:50 parts by weight, respectively.
