Product Introduction
Liantu, one of the leading manufacturers and suppliers in China, offers you not only high quality Waterproof Silicone Tape Waterproof Silicone Self-Fusing Tape | 100 PSI Emergency Seal at the best price, but also excellent additional services. Welcome to wholesale customized tapes made in China from our factory.

 

Waterproof silicone tape

Stop active leaks instantly. Liantu® Waterproof Silicone Tape handles 100 PSI and 260°C without adhesive. Fuses to itself even on wet, oily, or dirty pipes. Marine-grade, UV-stable, and residue-free.

Self-fusing silicone tape is a unique adhesive free product that quickly fuses to itself to create a moisture and corrosion resistant continuous seal for electrical insulation, pipe and hose repair, or anywhere a quick and residue free wrap is needed.

The "Emergency Nightmare" vs. The Liantu Solution

A leaking pipe at 2 AM is a disaster. Ordinary tape makes it worse. We engineered the "Instant Fix."

The Emergency Nightmare (Customer Pain Points) The Liantu Professional Solution (Our Solution)
"The Wet Surface Rejection": Standard tapes require a clean, dry surface to stick. If a pipe is spraying water or oily, adhesive tapes just slide off. Adhesive-Free Atomic Fusion: This tape contains no glue. It fuses only to itself via molecular cross-linking. It doesn't care if the pipe is wet, oily, or rusted-it creates a mechanical "constrictive" seal that is 100% independent of surface conditions.
"The High-Pressure Pop": Most patches "balloon" and pop the moment water pressure increases. Hydrostatic Compression (100+ PSI): By stretching the tape during application, you store mechanical energy. Once fused, it acts like a high-tensile structural sleeve that can handle significant internal pressure, stopping active leaks where glues fail.
"UV & Ozone Degradation": Outdoor repairs on boats or garden pipes often fail because sunlight "bakes" the tape until it cracks and leaks again. Inorganic UV Immunity: Silicone is naturally resistant to UV, ozone, and oxidation. It won't yellow, crack, or harden, providing a 20+ year outdoor service life in direct tropical sunlight or saltwater.
"The Maintenance Mess": Removing sticky "emergency" tape from a pipe often ruins the threads and requires hours of chemical cleaning. Zero-Residue Removal: Because there is no glue, there is no mess. When the permanent plumbing repair is ready, simply cut the silicone "boot" with a knife and it falls away, leaving the original surface 100% factory-clean.

Comparison: Liantu Silicone vs. The "Big Box" Competitors

A technical logic check for Marine Surveyors and Facility Managers.

Standard Duct Tape ($): Fails in moisture. Leaves a sticky mess. Status: Useless for Leaks.

EPR Rubber Tape ($$): Good for waterproofing, but melts at 90°C and cannot handle oil/fuel. Status: Medium Grade.

Liantu Waterproof Silicone ($$$): The "Rescue Grade." Handles 260°C, 100 PSI, fuels, and UV. Works underwater. Status: Mandatory Survival Gear.

Expert Insight: The Physics of the "Instant Weld"

[Liantu Rescue Engineering Lab] To stop a high-pressure leak, you are acting as an Engineer, not a hobbyist.

The Lead-In Anchor: Start wrapping 2 inches (50mm) before the leak.

The 300% Stretch: You MUST stretch the tape to 3 times its length. This tension is what forces the silicone molecules to interlock and fuse into a solid piece of rubber.

The "Hydrostatic" Seal: Because it creates a solid, one-piece rubber sleeve, it is one of the few materials that can stop an active leak under pressure without turning off the water source.

The Final Pass: Lay the final turn with less tension to ensure the end "melts" into the layer below.


 FAQ (Direct Solutions for Professional Procurement)

Q: Can I use this for underwater repairs?

A: Yes! Because it fuses to itself and not the object, you can wrap a leaking pipe while it is submerged. It is the gold standard for bilge pump and marine electronics repair.

Q: Is it safe for drinking water (Potable)?

A: Our silicone is chemically inert and non-toxic, making it safe for home plumbing and commercial food-grade environments.

Q: How do I remove it?

A: Just use a knife or scissors. The fused rubber will fall away cleanly like a dry "skin," leaving the surface underneath exactly as it was.
