VWM-TP
VOLSUN
VWM-TP waterproof insulation mastic tape is made from synthetic rubber and designed for sealing and insulating electrical cable connections, wire outlets, grounding wires and irregular joints. Its flexible, non-corrosive mastic form allows clean application and helps conform to uneven surfaces for reliable moisture sealing and electrical insulation.
The tape is suitable for low-voltage wire insulation, moisture-proof sealing of high-voltage cable joint grounding wires, wrapping of cable surfaces and protection of irregular electrical connections. It operates from -40°C to +85°C and provides an IP68 sealing grade.

Clean the cable, connector or substrate surface before application.
Make sure the application area is free from dust, oil, debris and other contaminants.
Cut the tape to match the size and shape of the area to be sealed.
Apply the tape evenly around the cable connection, wire outlet or irregular joint.
Press the tape firmly to improve surface contact and sealing performance.
Avoid excessive size deviation when cutting the tape, as this may affect installation quality and protection performance.
