Products introduction Well chosen basalt, diabase, limestone, dolomite and metallurgical coke are main raw materials for reinforced fibre. After complex substance is added in the main materials, fibre is made by spinning by high temperature furnace over 1100 degree celsius and surface treatment. Reinforced fibre includes rock cotton fibre, mineral cotton fibre and composite fibre. The recipe of kind of fibre is designed by requirement for friction coefficient, wear rate, impact strength and high temperature resistance in the recipe of friction and sealing material. With stable chemical component, it has all features as friction material reinforced fibre.
