SELF AMALGAMATING TAPES

A range of tapes which amalgamate (bond together) when applied under tension as an insulation wrap. They become a homogeneous, void-free mass without need for external heat or pressure.
The main applications are for high voltage electrical insulation, moisture proofing and corrosion prevention for telecommunication and other industrial uses.

The tapes are flexible and versatile in application. They can be easily applied by hand, contouring closely to irregular shapes and bends to form a permanent insulation layer or waterproofing barrier.

The life of the tapes exposed out of doors in the UK is expected to be several years. In enclosed locations, such as cables, the durability should be at least equal to that of the cables. Where tape may be subject to abrasion or exposure to weather an external covering with a high quality pPVC tape is recommended.

The most important tapes out of an extensive range are:

250l PIB Self Amalgamating Tape

For jointing/splicing and repair of a wide range of power and distribution cables up to 46kV. Used by postal and telecommunication authorities in conjunction with pPVC insulation tapes for making watertight seals, both above and below ground. Tapes can be applied for protection against corrosion on metal pipe work and waterproofing of electrical components.

2515/25l7 EPR Self Amalgamating Tape

For jointing/splicing and repair of a wide range of solid dielectrical power cables up to 69kV. Also used for insulating and waterproofing electrical components and connections at lower voltages. Can be used in conjunction with pPVC insulation tape.
