This distinctive property makes wollastonite an ideal performance mineral for a broad range of industrial and consumer applications including plastics, sealants, adhesives, elastomers, metallurgical fluxes, slag conditioners, ceramics, coatings, fire resistant construction board, stucco and glass. NYCO produces a diverse line of high aspect ratio, powder and ultrafine grades. Wollastonite?s reinforcing properties, its low hydroabsorptivity, its thermal stability and conductivity, low resin demand and chemical purity make it a value added, functional filler. Wollastonite is also non-hazardous making it a key ingredient in the replacement of asbestos.
