Powdertech’s
Sustainable Friction Material
Powdertech presents new hematite (Fe2O3) particles, which are spherical in shape with a large particle size as well as have a dense porous structure inside the particles. It is a sustainable friction material compatible with future developments in friction material formulations of the brake pad industry. The hematite is sintered into stable ceramic spheres which are easily compounded with other environmentally friendly friction materials.
Magnetite (Fe3O4) is commonly used as friction material since it reduces the need for high levels of copper and other metal powders. Hematite (Fe2O3) has been determined to not change coefficient of friction in high temperature braking applications. It has been shown to give improved brake performance and is useful for ceramic, hybrid and semi metallic pads.
