Mineral Fiber is chosen Basalt, Diabase,Limestone, Dolomite and metallurgical coke as raw material.Adding certain composites, the main production process is spinning, through the high temperature furnace more than 1080 oC and then through water slag, high speed cutting and organic surface treatment and refined fiber. It is a ideal reinforcement fiber for making friction products..
