asbestos paper

 The asbestos paper of BT (asbestos paper) GOST 23779-79 is made on the basis of chrysolitic asbestos (asbestos crumbs) GOST 6102-94. Table of contents of asbestos 98-99%. Used for heat-insulation of hot surfaces (caldrons, pipelines, thermal electrical heater ), in a production and heat treatment of metals, sheet and and so on.

Temperature of the insulated surfaces: to + 500°C. It is stable against fires and explosions. Bar to the senescence, rotting and other biological influences. Produced in rolls breadthways 1000 mm and weighing 80 kg .Shelf-life — 8 years from the day of making.
