Fiberglass Heat Cleaned Fabrics - Plain - Premium Grade MIL-C-20079H Type I Class 3 and Type I Class 9


1200°F / 648°C Continuous Exposure: Higher Intermittent

FlameShield™ high temperature, heat and flame resistant thermal insulating woven fiberglass cloth is heat treated to remove organics, set the weave dimensionally and reduce fray and loose fibers. Meets MIL-C-20079 (Type I Class 9 and Type I Class 3) along with US Coast Guard 164.009.

Used as a marine lagging fabric and in nuclear applications as a covering for insulation and board.

Designed for continuous operation at 1200°F / 648°C

Fabric is available in two weights; 8.5 oz/sq/yd (.018" thick) (Type I Class 3) and 18.0 oz/sq/yd (.032" thick) (Type I Class 9).  Roll width is available as 60 inches.

This fabric is also available with a self-adhesive backing.  The adhesive is acrylic based, and will burn-off or vaporize at temperatures above 400°F.  If prolonged use of the self-adhesive fabric above 400°F is desired, then alternate securing methods such as fasteners, wire or clamps should be used.  Personnel should avoid inhaling fumes from the PSA.
