Nordkalk W400 is characterized by different particle sizes and low, medium or high aspect ratio (L/D). In addition, wollastonite products are available surface treated, e.g. in plastics to enhance dispersion in polymer resin. Due to its unique chemical composition, particle structure and high brightness, wollastonite offers many advantages for glazing and body formulations in ceramic applications. Wollastonite is used as a functional filler in paint & coating applications, where technical requirements are high.
