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. • Highly resistant to prolonged immersion in water and has excellent resistance to ozone. • The product can be removed cleanly from most substrates, making it suitable for temporary repairs. • Supplied in an easy to handle and apply tape form. The product is interleaved with a disposable plastic liner.

Care should be taken to avoid direct contact between the tape and petroleum-type solvents and oils. Oils may affect the electrical properties of the tape. • The rolls should be stored flat on their cut edges in the original packaging. The product must be protected from dust, heat, moisture, direct sunlight and solvent fumes. Storage temperature between +10°C and +35°C. Under these conditions, the storage life of the tape in a temperate climate will be at least two year.
