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.
