APPLICATIONS For jointing and repairing a wide range of power and distribution cables up to 46 kV. For making watertight seals at polyethylene sleeve joints on polyethylene-sleeved telephone cables both above and below ground. For general-purpose protection and waterproofing. For insulation, waterproofing and protection of electrical components. For corrosion protection of metal pipework. For protection of joints against seawater in marine environments. For general-purpose DIY temporary repairs. For waterproofing and protecting cables and components on satellite dishes. PRODUCT BENEFITS Good physical and electrical properties with a high degree of stability under conditions of use. The tape amalgamates rapidly when applied under tension to provide a void-free homogeneous wrapping, without the need for external heat or pressure. Compatible with a wide range of rubber and plastic dielectric cable insulation. These include polyethylene, cross-linked polyethylene, ethylene propylene rubber, PVC, butyl and neoprene. Compatible with other Scapa electrical tapes, including PVC tapes. Highly resistant to prolonged immersion in water and has excellent resistance to ozone.
