Mineral Fiber

  Features of Mineral Fiber



    1.The softening point of mineral fiber is about 1200 ℃.


    2.The fiber appearance is smooth and intact.


    3.Mineral fiber has low shot content.


    4.Brake pads with mineral fiber has low  braking noise.


    5.Mineral fiber has excellent dispersion and it is suitable for different types of  blender mixer to mix.


    6.Mineral fiber is very safe when using, and it will not cause any harm to human.


    7.Mineral fiber has no pollution, and it is asbestos-free fiber by the third-party testing.

APPLICATION

Application of Mineral Fiber


1. Application :Disc Brake Pads, Brake Linings, Clutch Facings and other Industrial Friction Materials.

2. Mineral fiber could adapt well to the development of friction materials industry. Brake lining with mineral fiber has the performance of smooth and reliable braking, excellent high temperature performance, high wear resistance, low noise and long life. Mineral fiber is very popular in the industry of friction materials.
