There are two major categories of wollastonite products: low aspect or powder grades, and high aspect grades. These two categories of product are differentiated by the degree of acicularity, meaning the ratio of length to width of the crystals.  Within each category, individual products are further differentiated by grade, physical and chemical properties, and by surface additives which can enhance the mineral’s performance.

Depending on the nature of the specific application that is involved, some of the more important benefits that wollastonite can offer are the following:

	Improved dimensional stability.
	Greater high temperature stability and better resistance to heat distortion.
	Greater resistance to corrosion and mildew.
	Improved weather resistance and decreased vulnerability to ultra-violet degradation.
	Enhanced surface integrity accompanied by greater scratch and mar resistance.
	Improved friction stability.
	Noise reduction.
	More uniform heat transfer properties.
	Greater resistance to cracking and chipping.
	Improved strength and stiffness properties.
	Reduction in drying and curing times.
	Reduced shrinkage.
