Frictional lining type E-BF

Products > Friction lining > Frictional lining type E-BF

Frictional lining, type E-BF is made on the basis of synthetic resins, synthetic rubber, non-metallic fillers, mineral fibres, correctors and stabilizers of friction coefficient. Use of pulp of aramid fibre in the lining guarantees preservation of high thermal and chemical resistance and wear resistance of the lining during operation. This material is made with hot pressing technology. Then, after pressing process, frictional elements are subjected to special thermal treatment stabilizing the frictional and physical-mechanical properties.

Application

Frictional lining, type E-BF is applied in general industrial brakes and clutches. The material is designed for work in oil.
