Item: HB1104
Mastic seal tape
Features:
1. It has good bonding strength to the tubing of aluminum, copper, lead for oil removal and insulating tubing.
2. It has good air-tightness, sealing, adhesion, weathering resistance, ageing resistance, and electrical property in insulated cables connectors.
Applications:
1.
It is used with cable accessory (cold or heat shrinkable materials) for insulation, filling and sealing.
2. It is applied to joints of the ends or middles of cables (10kV or high voltage of more than 10kV).
3. It is the semi-conductor outside the cable, When the semi-conductor layer is cut off, it will be winded with the mastic tape
4. The mastic tape takes effect of electrical stress evacuation, insulation and filling the void.
