High dielectric strength

The tape is ideal for insulating cables and electrical lines.

Highly compatible with PE, PVC, butyl, neoprene etc.

Can be used in a wide range of sectors, e.g. the vehicle and electrical sectors

High degree of elasticity

The tape moulds to the base material extremely well.

  • The surfaces to be sealed must be dry and free from dust and grease.

  • To achieve perfect adhesion and a waterproof seal, wrap the tape tightly around the material to be processed and then overlap.

  • The shrink tape is only UV-resistant in certain cases and should therefore be protected from direct sunlight.
