It is a high quality, high specification self-amalgamating/self-fusing tape. Suitable for permanently waterproofing of electrical cables and cable joints. Can also be used for fast, temporary repairs to hoses and water pipes. Completely water and UV resistant. Used to joint and repair a wide range of power and distribution cables up to 46kV. Used for making watertight seals when jointing cables, both above and below ground. Good physical and electrical properties. Excellent self-amalgamation, heat and ageing characteristic.
