Thermal protection sleeve

braidedfiberglasssilica

Product Overview
Alumina fiber braided sleeve provides high-temperature thermal protection and dimensional stability for industrial components and wiring where conventional fiberglass or silica sleeves are insufficient.

Material & Construction

• Made from continuous alumina (aluminum oxide) fibers, braided or woven into a flexible tubular sleeve.
• High alumina content for extended temperature resistance.
• Low thermal conductivity for effective insulation.
• Maintains dimensional stability under extreme heat and thermal cycling.
• Non-combustible and electrically non-conductive.

Typical Applications

• Protection of furnace and kiln components
• High-temperature hoses and tubing insulation
• Thermocouple and sensor wire protection
• Molten metal handling and casting environments (with additional surface protection as required)
• Heat treatment, metallurgy and glass processing lines
• Shielding cables and components near heat sources

Thermal Performance Characteristics

• Suitable for continuous exposure to very high temperatures
• Retains structural integrity under radiant heat and thermal shock
• Outperforms standard fiberglass and silica sleeves in extreme conditions

Installation & Use

• Slide the sleeve over hoses, cables or components to be protected
• Cut to length with appropriate cutting tools
• Ensure full coverage of heat-exposed zones
• Secure sleeve ends mechanically or with fittings for high-vibration environments

Limitations

• Not designed as a pressure-bearing or structural component
• Lower abrasion resistance compared with coated or metal-reinforced sleeves
• Chemical compatibility must be verified for aggressive media
• For heavy abrasion or direct molten-metal splash, add surface protection or a coated option
