Phenolic cotton cloth sheet

 Phenolic cotton cloth sheet GOST 5-78 layered sheet material on the basis of the cotton fabric impregnated heat-convertible binding  substance . It is well processed by all kinds of machining. It is applied to manufacturing pinion, plugs, bearings of sliding, panels, slider on power-saw benches, linings for amortisation products of technical purpose.Products from textolite provide noiselessness in work, considerably the big service life, smaller relative density in comparison with metal. It is long admissible working temperature from-65С up to 105С. It is produced by sheets in width from 450 to 1000 mm, length from 600 up to 2000 mm, thickness from 0, 5 up to 200 mm.
