Reinforcing the future with Nordkalk W-Series

Nordkalk W-Series

The wollastonite products in Nordkalk’s W-Series are classified based on the aspect ratio and size of the particles. In addition, Nordkalk’s wollastonite products are available with various surface treatments, which improve the coupling between the wollastonite and polymer and thus boost the functional properties of wollastonite.

Due to the first-class quality of Nordkalk’s wollastonite products, the W-Series products are used as a functional filler in applications that require high technical quality. Wollastonite improves, for instance, the mechanical properties and wear resistance of various plastic compounds and applications such as in the plastic components of car interiors, exteriors and engine compartments and in a variety of electrical insulation plastics.

Due to the diverse physical-chemical properties of wollastonite it is used as a filler in many paint and coating applications. In various industrial paints and coatings, wollastonite improves corrosion resistance, strengthens the film and reduces cracking. Wollastonite improves, among other things, the heat resistance and mechanical properties of powder coatings and the durability of road-marking paints.

In ceramics and friction applications, the chemical properties of wollastonite offer many process technical benefits and as a white, strength-increasing filler it enhances mechanical properties.
