Asbestos Board

asbestos board

[as′bes·təs ‚bȯrd]
A sheet of fire-resistant material made from asbestos fiber and portland cement.

Asbestos Board


fireproof insulating material made from chrysotile-asbestos fibers impregnated with bakelite. It is produced in the form of sheets 1,000 mm in length, 1,000 mm in width, and 2–10 mm in thickness. Asbestos boards are used as facing and heat-insulating material, for sealing joints in machines and equipment, and also in the manufacture of gaskets. Such boards may also serve as filler in combined asbestos-metal linings installed in pipelines operating under pressures of 4 meganewtons per m2 (40 kilograms-force per cm2) at temperatures ranging from 300° to 400° C.
