3M Scotch 23 Tape – Linered Rubber (EPR) Self Amalgamating Tapes
3M Scotch 23 Tape is a highly conformable 0.76mm thick, high voltage jointing and an EPR (Ethylene Propylene Rubber) based self amalgamating tape.
Scotch 23 Tape can be used as an insulation for low voltage applications as well as insulation for cable joints up to 69kV.
The tape is non-vulcanising, shelf-stable tape with excellent electrical properties that are unaffected by degree of stretch and forms part of the 3M Scotch Electrical Tapes.

Specification – 3M Scotch 23 Self Amalgamating Tape
Scotch 23 tape, manufactured by 3M Electrical, is based on ethylene propylene rubber and be capable of operation at the emergency cable temperature of 130°C (266°F). The 3M scotch tape must be capable of being applied in either the stretched or un-stretched condition without any resulting loss in either physical or electrical properties. The Scotch tape must not split, crack, slip or flag when exposed to various environments (indoor and outdoor). The tape must be compatible with all synthetic cable insulations. The tape must have a dissipation factor of less than 5% at 130°C (266°F) and must have a shelf life of 5 years.
3M Scotch 23 Tape
Linered Rubber (EPR) Self Amalgamating Tapes Features
- 3M Scotch 23 tape is non-vulcanising and shelf-stable with excellent electrical properties
- A special polyester liner which will not stick to the tape upon unwind
- Scotch 23 tape can be stretched up to 100% to give void-free, moisture-resistant insulation
- Up to 90°C continuous operating temperatures and 130°C emergency overload temperature
- Self-fusing self amalgamating tape
- Based on Ethylene Propylene Rubber (EPR)
3M SCOTCH 23 TAPE – Applications
- Primary electrical insulation for jointing cable from 600V to 69kV on all solid dielectric cables
- Primary insulation for building stress cones on cables up to 35kV on all solid dielectric cables
- Jacketing on high-voltage joints and terminations
- Moisture sealing electrical connections
- Bus bar insulations
- End sealing high-voltage cables
- Scotch 23 Electrical Tape should be applied in successive half lapped, level-wound layers until desired build-up is reached
- To eliminate voids in critical areas, highly elongate 23 Tape
- Stretch tape in these critical areas just short of its breaking point – doing so will not alter its physical or electrical properties
- In less critical areas, less elongation may be used – normally, 3M Scotch 23 Tape is stretched to ¾ of its original width in these less critical areas
- Always attempt to half-lap to produce a uniform build-up
- When using 23 Tape for jointing cables from 35kV to 69kV, always elongate the tape throughout the entire joint
