Self-Fusing Silicone Waterproof Tape — Extreme High-Temperature Industrial Sealing Solution

The WNRLN-SFST-25 is a premium self-fusing silicone rubber waterproof tape specifically engineered for high-temperature industrial applications where conventional butyl or vinyl tapes fail. Rated for continuous operation at 260°C with short-term peak resistance up to 300°C, this tape provides unmatched thermal stability for pipe sealing, exhaust system repair, and engine compartment insulation.

Key Features & Benefits

  • Extreme Temperature Resistance: Continuous operating range from -60°C to 260°C, with short-term tolerance up to 300°C — ideal for steam pipes, exhaust manifolds, and turbine components.
  • True Self-Fusing Technology: Bonds only to itself under tension with no adhesive layer, eliminating sticky residue and ensuring a clean, permanent seal that improves over time.
  • Superior Electrical Insulation: Dielectric strength ≥ 8 kV/mm provides reliable insulation for high-voltage electrical connections in harsh thermal environments.
  • Chemical & UV Resistant: Silicone formulation resists oils, solvents, moisture, UV radiation, and ozone — suitable for both indoor and outdoor industrial installations.
  • High Mechanical Strength: Tensile strength ≥ 2.5 MPa with elongation at break ≥ 300%, allowing the tape to conform tightly around irregular shapes and withstand vibration.
  • No Curing Required: Fuses instantly upon wrapping — no heat, no tools, no drying time. The seal strengthens over 24 hours at room temperature.

Typical Applications

  • Industrial steam pipe joint sealing and leak repair
  • Exhaust system and muffler wrapping in automotive and marine engines
  • High-temperature electrical cable insulation in furnaces and ovens
  • Turbine, boiler, and heat exchanger component sealing
  • Emergency repair of hot water and thermal fluid piping
  • Protective wrapping for hydraulic hoses exposed to radiant heat
