More Information
Summary:Said braking block is mode up of main raw materials (steel fibre, glass fibre, reduced iron powder, synthetic rubber, barium sulfate and activated rubber powder), adhesive (modified resin) and strengthening material (metallic sheet) through such technological steps as proportional mixing of raw materials, stepped heating and press moulding, and insulating solidification. It features moderate friction coefficient, small abrasion, oil and water resistances, no cracking, long service life and no use of asbestos.
