What is Self-Fusing Silicone Tape？
Self Fusing Silicone Tape, also known as Self Fusing Silicone Tape or Amalgaming Silicone Tape, is a special tape made by extruding 100% high-performance silicone rubber elastomer. Its most unique feature is that it does not contain any adhesive, but is wrapped layer by layer after stretching, and the silicone material undergoes chemical bonding between them, permanently fusing into one.
This type of tape does not rely on adhesion to the surface of an object, but rather "sticks to itself" - after stretching and wrapping, the layers merge into a seamless whole.
Core Features
• No adhesive, no residue - only related to oneself; Stripped clean, very suitable for temporary and on-site maintenance.
• Instant water tight and air tight sealing - prevents leaks in pipes, hoses, and radiators within minutes.
• High voltage insulation - up to 8000 V per layer; dielectric strength ≥ 20kV/mm.
• Extreme temperature resistance - operating temperature range of -60 ° C to+260 ° C, flame retardant option (UL94 V-0).
• Anti aging and weather resistance – specially anti ultraviolet, anti ozone, anti corona, anti-corrosion, and long service life.
• High ductility and formability - 300%+elongation wraps around irregular shapes such as connectors and busbars.
• Chemical corrosion resistance - resistant to fuel, coolant, acid, alkali, and solvents.
Main application scenarios
• Electrical insulation: cable joint insulation protection, harness wrapping, motor lead insulation, high-voltage terminal sealing
• Pipeline and hose repair: emergency repair of leaking pipelines and hoses, production of pipeline insulation and anti-corrosion layers
• Car maintenance: engine compartment sealing, wire harness protection, emergency repair of fuel/water pipes, anti-corrosion of metal connectors
• Ship and Outdoor: Rigging wrapping for ships, sealing and waterproofing of outdoor equipment
• Tool handle anti slip: Wrap the tool handle to provide anti slip grip and vibration protection
• Emergency repair: rapid repair in multiple scenarios such as home maintenance, emergency rescue, military use, etc
• Industrial sealing: emergency replacement of O-rings, busbar insulation, special manufacturing for high pollution environments
Frequently Asked Questions
Q: How does it work without adhesive?
A: Stretching activates self-fusing properties—silicone molecules bond chemically when wrapped under tension
Q: How long does it take to bond?
A: Begins fusing within seconds to minutes; fully cures within 24 hours
Q: Can it be used underwater?
A: Yes—can be applied on wet surfaces or even underwater
Q: How to use Self Fusing Silicone Tape?
A: 1.Clean the surface to be repaired and hands, remove oil stains and dust
2.Tear off the tape packaging and remove the 1-2 inch release film
3.Apply the tape firmly to the repaired surface and stretch it to 2-3 times its original length
4.Overlap and wrap layer by layer (recommended to overlap more than 50%), ensuring that each layer is tightly adhered to the previous layer
5.The tape begins to fuse within minutes and forms a permanent seal within 24 hours
