  • Flame-retardant cross-linked composition and flame-retardant cable using same
    Patent number: 4549041
    Abstract: The flame-retardant cross-linked composition is produced as follows: A first compound of a metallic hydrate and a polyolefin resin free from any halogen is mixed with a silane-grafted polyolefin resin free from any halogen to form a second compound; and the second compound is silane cross-linked to form the flame-retardant cross-linked composition. The metallic hydrate is mixed in an amount of about 50 to about 200 parts by weight per about 100 parts by weight of the polyolefin resin and the silane-grafted polyolefin resin, and the polyolefin resin is mixed in an amount of about (100-x) parts by weight where x is the amount of the silane-grafted polyolefin resin and about 10.ltoreq.x.ltoreq. about 80 parts by weight.The flame-retardant cross-linked composition is excellent in flame retardancy, thermal resistance and forming property and further advantageous in production cost as compared to the conventional flame-retardant composition.
