Imerys M325 WOLLASTOCOAT® Wollastonite
Categories:	Ceramic; Oxide; Silicon Oxide; Other Engineering Material; Additive/Filler for Polymer
Material Notes:	Wollastonite is a naturally occurring white mineral with an acicular (needle-shaped) particle structure. This distinctive particle morphology makes wollastonite an ideal performance mineral for a broad range of industrial and consumer applications, including polymer reinforcement; coatings; construction/architecture reinforcement; enhancing friction stability in discs, lings, and brakes; and metallurgy. .Information provided by NYCO Minerals, subsequently acquired by Imerys.
