1-Mineral fibre (mineral fiber)
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 fibre products. The fibre products we manufactured are ideal material which can replace asbestos in friction materials. We have mineral fibre, ceramic fibre, nature cellulose fibre, composite fibre and so on. Brake linings made from our fibre 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.

4-Composite fibre (composite fiber)
Main components: man-made rockwool, organic fibres and surface treating agent
Characteristics and applications:
Good decentrality, can be used well in all types of mixers, in the process of producing, we put in organic fibres and do some treatment on the surface of rockwool to make it has good cold effect, can be used well in brake linings, and don’t need additional organic fibre.
