Rock wool mineral fiber can be applied to friction&sealing, coating, Insulation, road engineering and etc.
Our products are used in mainly friction applications. Braking is the result of a surface interaction between brake disc and friction material. The performance of the brake system is influenced by the formulation of the friction material. A typical friction material consists of 10 - 20 raw materials. Each raw material has a unique chemistry, size and shape and therefore a unique functionality. Finding the right balance between these functionalities is crucial in the development of friction formulations. Each raw material, including mineral fibres, has a specific function. The main purpose of mineral fibres is to facilitate other raw materials to work properly under any braking condition. They can also be engineered for different contributions to friction formulations from a tribologic point of view. The final performance of the friction material always depends on the synergy between all raw materials.
● Non asbestos
Our slag wool mineral fiber has no asbestos and can be ideal alternatives of asbestos for friction application. What’s the most important, it is at far lower price than asbestos.
● Low Ignition loss
At high temperature, some inorganic substances in mineral fibers will be burned off, resulting in fiber loss on ignition rate. Slag wool mineral fiber are pure inorganic fiber without any organic composition, so it hardly have a fiber burn rate.
● Very low shot content
The HB11X shot content can be controlled below 2% after six times of shot removal process. Shot will bring wear and noise. Shot content is one of the standards to velue fiber quality.
● Excellent stability
Excellent stability, temperature resistant, corrosion resistant, moisture resistant and wear resistant.
