Asbestos paper
Asbestos paper is used to insulate hot surfaces (boilers, pipelines, steam pipelines, heating elements), in the production and heat treatment of metals, casting, etc.
Asbestos paper is produced in rolls of up to 1000 mm wide, weighing> 70-80 kg and 0.65 and 1.0 mm thick.
- temperature of insulated surfaces up to + 500°С;
- content of asbestos 98-99%;
- elastic, durable;
- does not emit harmful gases into the environment;
- resistant to aging, decay and other biological influences.
