MICA POWDER
Introduction of YAMAGUCHI MICA POWDER (Calcined Mica Powder for friction materials)
It is generally believed that calcined mica is more effective than non-calcined mica when it is used as friction material for brakes. It will improve the physical properties of brakes substantionally. Yamaguchi's "NCF-932" calcined mica, has been top of the line product for more than ten years on the primary market with our superior technical knowledge and quality control.
