ALENOR DE Electrical Insulating Mastic Tape

ALENOR DE Electrical Insulating Mastic Tape

ALENOR DE Electrical Insulating Mastic Tape – a self-sealing electrical insulating material based on synthetic rubber. After installation under tension, it forms a continuous, uniform layer without interlayer voids.

Product composition: a permanently tacky compound based on non-vulcanized rubber, protected by a release paper liner.

Scope of application:

    • • electrical insulation of low- and medium-voltage cable connections
    • • sealing against moisture and condensation
    • • restoration of damaged insulation
    • • protection against corrosion and aggressive environments
    • • sealing of cable entries
    • • mechanical protection against vibration and abrasion
    • • repair and maintenance works

Advantages:

    • • clean installation without contamination of hands or surfaces
    • • uniform elasticity along the entire length
    • • self-sealing in case of cuts and punctures
    • • long service life
    • • environmentally safe material
