Basic Info
Continuous Temperature: up to 260°C / 500°F*
Elongation: up to 300%*
Material: Silicone Rubber
Widths: 25 / 38 / 50 / 100 mm

APPLICATIONS
Automotive & EV: Protect the connections that keep the vehicle moving.
Use around: Wiring harnesses • Engine‑bay wiring • Cable joints • Electrical connectors • Sensors • Battery‑related wiring • Hose connections.
It is the ability to wrap, seal and protect shapes that are difficult for conventional tapes or sleeves to handle.
Electrical Insulation: Insulate wire splices, cable joints, terminals and connectors.
Waterproof Sealing: Create moisture‑resistant seals around connections, joints and exposed components.
Hose & Pipe Repair: Wrap damaged or leaking hoses and pipes as an emergency or maintenance solution, subject to the pressure and media compatibility of the specific grade.
High‑Temperature Protection: Protect components exposed to elevated temperatures where the selected silicone grade is suitable.
Harness Protection: Bundle and protect wires and cable harnesses without adhesive.
Connector Sealing: Conform around irregular connectors, terminals and transitions where ordinary tape struggles to create a continuous seal.
Outdoor Protection: Resist environmental exposure including UV, ozone and moisture.
Industrial Maintenance: A compact repair material for maintenance teams dealing with unexpected failures in the field.
DESIGNED FOR THE SHAPES OTHER TAPES STRUGGLE WITH
Silicone Self‑Fusing Tape is especially useful around:
Connectors
Cable joints
Hose fittings
Elbows
Branches
Irregular surfaces
Transitions between different diameters
No pre‑shaped sleeve required.
One roll can adapt to many different shapes.
PROTECTION THAT MOVES WITH YOUR ASSEMBLY
A rigid repair can become a new failure point.
Silicone remains flexible.
That means the finished wrap can accommodate:
Vibration
Bending
Thermal cycling
Cable movement
Expansion and contraction
This flexibility is one reason self‑fusing silicone tape is used in automotive, marine, industrial and electrical applications

FAQ
What is self‑fusing silicone tape?
It is a non‑adhesive silicone rubber tape that fuses to itself when stretched and wrapped with overlap, creating a continuous rubber‑like protective layer.
Does silicone self‑fusing tape have adhesive?
No. It does not rely on a conventional adhesive backing. It bonds to itself through the silicone material.
Will it leave sticky residue?
Normally no. Because there is no conventional adhesive layer, it does not leave the typical sticky residue associated with adhesive tapes.
Is it waterproof?
When properly wrapped with sufficient overlap and tension, the fused silicone layer can provide a watertight seal.
Can it repair a leaking hose?
It can be used for emergency or maintenance sealing of suitable hoses and pipes, but pressure, temperature, fluid compatibility and damage severity must be evaluated for the specific application.
Can it be used on electrical cables?
Yes. Silicone self‑fusing tapes are widely used for electrical insulation, cable splicing, connector sealing and harness protection. For electrical systems, the required voltage and dielectric specifications must match the selected grade.
How hot can it get?
Suitable grades can provide continuous service around 200–260°C, while short‑term exposure can be higher. The exact temperature rating must be confirmed from the specific product TDS
