The Resin Coated Rock Wool Fibre is short fibre made of basalt and minerals through process of melting, spinning, resin coating and breaking. It is suitable for asbestos free friction materials, disc pad particularly.
Product advantages include:
- Low cost, help to substantially bring down the cost of asbestos free friction material.
- Comparing with glass fibres and wollastonite, it reduces noise and judder of friction material as well as improving the wear resistance.
- Comparatively low melting point makes the resin coated rock wool softer at high temperature, which reduces the wear of rotor as well as assisting adhesion at high temperature. So it improves the wear resistance of friction materials at high temperature. It is the important substitute of asbestos for friction materials.
