Semi-conductive Water Blocking Tape

Semi-conductive Water Blocking Tape

Product Characteristics:

Good hygroscopicity, large expansion, quick expansion speed;

Small resistance, semi-conductive which could weaken strength of electric field ;

High mechanical strength which would be good at cable lapping and longitudinal wrapping;

Good heat resistance, good moment heat resistance..

Product Usages:

It’s mostly suitable for water-proof electric cable of medium, high and super high voltage, others of shield requirements for communication, control & signature and instrument cables for semi-conductive water blocking. It could play a part of water blocking, buffer and shield. And it has no causticity.
