Alumina Fiber Sleeving

Alumina Fiber Sleeving

The alumina continuous fiber braided sleeving is made of new-type continuous alumina fiber yarns through an optimized braiding process. It has the advantages of light weight, low heat capacity, excellent thermal insulation performance, good high-temperature heat insulation and fireproof performance, stable chemical properties, corrosion resistance, oxidation resistance, etc. It also has excellent characteristics such as high pressure resistance, high temperature resistance, and electrical insulation. It is applied to the thermal protection and thermal sealing of various pipelines, and can also be used in combination with other materials to make packing seal components. It has good extensibility, and thermal insulation sleeving with different expansion rates can be produced according to different yarn strengths and textile processes.

Features of Alumina Fiber Sleeving

  • High-Temperature Resistance: Alumina fibers in the sleeving can endure high temps. They often withstand up to 1200°C (2200°F) and even more briefly.

  • Thermal Insulation: The sleeving offers great thermal insulation, blocking heat transfer and safeguarding nearby components.

  • Flexibility: Despite high - temp resistance, the alumina fiber braided sleeving stays flexible, facilitating easy installation on various shapes.

  • High Tensile Strength: It shows high tensile strength, ensuring durability against mechanical stress.

  • Corrosion Resistance: Alumina fibers resist corrosion from chemicals and harsh environments.

  • Electrical Insulation: These fibers have good electrical insulation, fitting for electrical applications.

  • Moisture Resistance: Alumina fibers don't absorb moisture, which is beneficial in some uses.


Applications of Alumina Fiber Sleeving

  • Aerospace. Cable and insulation wraps, fire zone cable protection, fire barriers, thermal shields.

  • Industrial. Cable and insulation layers, hose protection, fire zone cable protection, fire blanket applications.

  • Electrical. Heater wire insulation, thermocouple insulation.
