Very High Temperature, Heat & Flame Resistant Thermal Insulating
Vermiculite Coated Braided Fiberglass Sleeve
very high temperature heat and flame resistant vermiculite coated fiberglass sleeve
Very High-Temperature Vermiculite
Coated Braided Fiberglass Sleeve
This high temperature, heat and flame resistant thermal insulating vermiculite coated braided fiberglass sleeve will withstand temperatures of 1500°F / 815°C continuous exposure.  The base high temperature braided fiberglass sleeving is fabricated from high quality type E fiberglass that will not burn.  The sleeve is then coated with a vermiculite dispersant.

This material resists most acids and alkalis and is unaffected by most bleaches and solvents.  It is highly flexible and conformable.

The base fiber is manufactured to the specifications of ASTM D-578, ASTM committee D13, and subcommittee D13.18.
Applications for this product include thermal insulation, protection of wires, cables, hose, tube and pipe as well as affording personnel protection and energy savings.

The vermiculite coating also adds abrasion resistance to the sleeve.

Benefits of our High-Temperature Fiberglass Heat Protection Products

Fiberglass offers excellent heat resistance, retaining more than half of its room temperature tensile strength at 675°F / 357°C, and more than 25% at 875°F / 468°C.  It begins to soften at 1500°F / 815°C and melts near 2050°F / 1121°C. Non-combustible and excellent thermal conductivity to dissipate hot spots; high resistance to chemicals and unaffected by UV light.
