Sustainable Friction Powder
High Performance Brake Pad Applications
Sustainable Friction Material
Powdertech introduces patented hematite (Fe2O3) particles, which are spherical in shape with a large particle size and a dense porous structure inside the particles. The hematite is sintered into stable ceramic spheres which are easily compounded with other friction pad materials. Our sustainable friction material is compatible with formulations designed for high performance brake pad applications.
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 maintain coefficient of friction in high temperature braking applications. Hematite has been shown to give improved brake performance compared to magnetite, and is beneficial for ceramic, hybrid and semi metallic pads.
