Self-bonding waterproof mastic tape is a self fusing electrical insulating and waterproof tape, insulation for motor leads rated up to 1000volts, primary electrical insulation for bus bar connections rated up to 35KV, padding for irregular shaped connections, waterproof sealing protection of overhead insulated wire joint, Moisture sealing for ground wire, cable and wire connections. It is a versatile, adaptable rubber tape used for insulating and sealing electrical components. Crafted from ethylene propylene rubber (EPR), it boasts a sturdy backing coated with a potent, thermally stable adhesive.
This tape, measuring 65 mils (1.65 mm) in thickness, enables rapid application buildup. It is meticulously engineered for the purpose of safeguarding against electrical issues and moisture infiltration. Ideal for application on copper or aluminum conductors rated at 90°C, it can handle emergency overload conditions up to 130°C.
Notably, self-bonding waterproof mastic tape showcases exceptional resilience to moisture and UV exposure, making it suitable for both indoor usage and outdoor application in various weather conditions.
Features:
1.Conformable for application over irregular surfaces
2.Compatible with solid dielectric cables and wires
3.Flexible over wide temperature range
4.Excellent weather and moisture resistance, sealing properties
5.Easy to use, no need heating and special tools
