Poly-isobutylene, flammable, black coloured tapes separated with plastic film against self – adhesion.

Main applications: this type of insulating tapes is mainly used for insulating connections of low current and television cables and wires and also for telecom cable jointing, anticorrosion prevention of pipelines, low and medium voltage power cable installation up to 36 kV but this latter – due to the flammability – only in cases when there is no heat effect. When using the tape at higher than 1 kV voltage level, these insulating tapes should be used together with potential controlling tapes. In addition to insulation and waterproofing these insulating tapes provide excellent self-vulcanising properties.
