Wollastonite is a naturally occurring mineral with many unique characteristics. Through advanced processing, its properties become valuable in a variety of end-use applications. Wollastonite increases the performance of many products including plastics, paints and coatings, construction materials, friction, ceramic and metallurgical applications, to name a few.

One of wollastonite's most unusual characteristics is its ability to cleave into needle-like crystals. Its high aspect-ratio fibrous particles are what makes it useful in many physical reinforcement applications.

Wollastonite's unique chemistry makes it a highly valued source of CaO and SiO2, in nearly equal proportions. Additionally, the surface treatment of wollastonite leads to superior performance in its use with a variety of organic systems.

The use of wollastonite in an ever increasing array of applications continues to grow. NYCO remains the reputable industry leader of premium quality wollastonite through it's over 50 years of operation.
