Wollastonite

Optimization of Wollastonite Fillers with Evonik Products

Wollastonite is a naturally occurring mineral composed mainly of calcium, silicon, and oxygen. Its composition makes it a versatile, stable filler that primarily enhances the strength and durability of materials.

Silane products like DYNASYLAN® are used for the surface modification of wollastonite. They improve the compatibility of inorganic wollastonite with organic polymers. This leads to a more uniform distribution of the filler and an improvement in mechanical properties. The use of silanes in the processing of wollastonite reduces material consumption and enhances the lifespan of the final product.
