Abstract
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.
Claims16
A zero halogen polymeric composition comprising:
- (a) a base polymer selected from the group consisting of at least two polyolefin polymers;
- (b) a filler comprising at least one substance selected from the group consisting of metal hydrates, oxides, carbonates, talcs, clays, molybdates, borates, stannates, graphite, carbon black, silicates and phosphates;
- (c) an additive comprising at least one substance selected from the group consisting of an antioxidant, an organosilane, a pigment and a lubricant;
- (d) an unsaturated dicarboxylic anhydride modified thermoplastic polymer;
- and
- (e) a nanoclay filler.
