MicaFort Phlogopite mica for brake pads
Phlogopite mica can be one of the mineral fillers used to make brake pads. Because of its platy structure and high thermal resistance, it is very suitable. They decrease the difference between the static and the dynamic coefficient of friction.
Other platy minerals, such as graphite, can do this as well but phlogopite delivers constant performance even under changes in pressure and temperature.
In comparison to many commercially available mica products, MicaFort Phlogopite grades offer a significant health and safety benefit due to their extremely low levels of free respirable silica. This is of particular significance for customers manufacturing products in a dry mixing process where exposure to respirable free silica can lead to serious illness and disease. One of the alternative minerals, quartz, is very abrasive causing additional machine wear and maintenance costs, which LKAB Minerals’ MicaFort does not.
To sum it all up, the technical benefits provided by MicaFort are:
- high thermal resistance
- a similar static and dynamic friction coefficients
- very stable behaviour despite pressure and temperature changes
- very low crystalline silica <0.1%
