Vietape SI7101 – Silicone Self-Fusing Tape
Part number
SI7101
Vietape SI7101 is a silicone self-fusing tape with no adhesive layer: stretched and wrapped tightly under pressure, the layers fuse into a durable, homogeneous protective layer. Working temperature -50 to 200 °C (short term up to 260 °C), dielectric strength above 18 kV/mm, for sealing, electrical insulation and leak repair in demanding environments.
Specifications
APPLICATION:
- Leak repair and sealing: pipes, connections, drainage systems
- Temporary or permanent sealing for leaks or protection
- Electrical and cable protection: splices and wires in harsh environments
- Waterproof joints that withstand high temperatures, weather and chemicals
- Automotive and industrial: moisture, corrosion and abrasion protection
