 Phenolic cotton cloth

Phenolic cotton cloth it is a layered sheet and shaped material on the basis of the cotton fabric impregnated heat-convertible binding.It is well processed by all kinds of machining. It is applied to manufacturing шестерен, plugs, bearings of sliding, panels, 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 materials.
