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.
Heat Treated Braided Fiberglass Sleeve for Wire, Cable, Hose,
Tube & Pipe Protection -
Exceptionally Clean Sleeving for Aviation / Marine / Clean Room Applications
High Temperature, Heat & Flame Resistant and Thermal Insulating
1200°F / 648°C Continuous Exposure:
Higher Intermittent

This high temperature, heat & flame resistant and thermal insulating braided fiberglass sleeve is fabricated from high quality type E fiberglass that will not burn and will withstand continuous exposure to temperatures of 1200°F / 648°C. This high temperature sleeve provides protection for wires, cables, hoses, piping and tubing.  Provides thermal insulation and personnel protection.

This sleeve is heat treated, which removes impurities and organics from the sleeve and also allowing it to operate at the top end of its temperature range without shrinkage or burn-off.  This sleeve is made from filament fiberglass fibers, and is not texturized, resulting in a sleeve that is extremely smooth and clean of loose fibers.  

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.
