Product Description:

High-silica self-adhesive tape is an inorganic, fire-resistant wrapping tape featuring a high-silica fiberglass substrate (SiO₂ content ≥95%) coated on one side with a high-temperature-resistant pressure-sensitive adhesive. It is **not** a silicone rubber self-adhesive tape. Its key characteristics include long-term temperature resistance of 1000–1300°C (with short-term peaks exceeding 1600°C), non-melting/non-dripping behavior, non-flammability, and self-extinguishing properties. Upon wrapping, it achieves "self-setting" (bonding via the fiber structure) rather than "self-fusing" (material amalgamation) when exposed to high temperatures.

Main Composition and Structure: High-purity high-silica fiber (SiO₂ ≥95%); not silicone rubber. The adhesive backing is typically silicone-based or ceramic-forming pressure-sensitive adhesive; it carbonizes and decomposes at high temperatures (>300–500°C), allowing the fiber itself to wrap tightly around the object and form a mechanical protective layer.

Temperature Resistance Range: Long-term use at 800–1000°C; instantaneous resistance up to 1300–1600°C (far exceeding the –50°C to 260°C range of silicone rubber self-adhesive tapes). It maintains electrical insulation properties at high temperatures but does **not** exhibit self-fusing adhesion at room temperature (unlike the "self-fusing" nature of silicone rubber tapes).

Application Scenarios:

Thermal insulation wrapping for high-temperature piping (e.g., exhaust pipes, turbocharger lines); binding and securing of motor and transformer coils; cable protection near furnaces in the metallurgy and foundry industries; fire-resistant sealing; thermal protection layers for aerospace and military applications; and flame-retardant wrapping for high-temperature areas in marine and rail transport.
