According to the adjustment of the state administrative policy and the transformation of the automobile friction materials to non-asbestos, our factory introduce advanced technology from Germany and specialized automatic production line of fiber products. The fiber products we manufactured are ideal material which can replace asbestos in friction materials. We have mineral fiber, ceramic fiber, nature cellulose fiber, composite fiber and so on. Brake linings made from our fiber products have many notable features such as braking stably, high temperature properties, little abrasion, low (no)noise and long life. They are very popular in friction materials manufacturers.
