Abstract: A fire or flame barrier material comprising an ethylene copolymer matrix, 150-220 parts by weight of aluminum hydroxide and 150-220 parts by weight of calcium carbonate or calcium-magnesium carbonate. The material can also include a lubricating agent, an elasticizer, calcium oxide, a polymer softening agent, a color-aging agent, and an antioxidant agent.

Abstract: A cable structure for telecommunication or power supply applications, comprising one or more conductors, each of which is surrounded by a micatape embraced by an insulating layer of heat resistant rubber. The conductors are embraced by a thermoplastic elastomer on the outside of which there is placed a braided metal armour. The structure has an outer sheathing of chlorine sulphonated polyethylene or ethylene propylene rubber. Used as a three-conductor power cable the conductors are twisted together inside the layer of thermoplastic elastomer.
