Alumina Fiber Tape

The alumina continuous fiber braided tape is woven from high-strength alumina continuous fibers. Different yarn specifications and weaving processes, which are suitable for different service temperatures and conditions, can be adopted to meet customers' requirements. Its continuous service temperature is around 1200 - 1300°C, and it has good resistance to molten metal corrosion. It is suitable for heat insulation, thermal preservation, sealing, electrical insulation, sound absorption, filtration, etc. in high-temperature environments.

  • Non-oxidizing.

  • Non-hygroscopic.

  • Low thermal conductivity.

  • High strength and high modulus.

  • Excellent chemical resistance.

  • Good abrasion resistance.

  • Fire and flame retardant.

  • Broad electromagnetic transparency and electrical insulation.


Applications of Alumina Fiber Tape

Aerospace

Thermal protection: Used for aircraft parts like wing leading edges and nose cones to block high-temp heat during re - entry or high - speed flight.

Engine parts: Manufactures engine insulation covers and seals, enhancing efficiency and reducing heat loss.


Power & Electrical

Cable insulation: Serves as insulation for high - voltage wires to prevent electrical issues.

Equipment insulation: Insulates electrical devices like transformers to improve heat dissipation.


Metallurgy

Furnace insulation: Lines high-temp furnaces, cutting heat transfer and protecting the structure.

Metal filtration: Makes filters for molten metal, withstanding harsh smelting conditions.


Chemical

Reactor insulation: Insulates reactors, boosting reaction efficiency and safety.

Pipe insulation: Insulates and seals chemical pipes, preventing heat loss and leakage.


Automotive

Engine insulation: Reduces engine heat transfer to the car interior.

Exhaust insulation: Lowers exhaust pipe surface temp and improves exhaust efficiency.
