Wollastonite is an acicular calcium silicate mineral used as a reinforcing functional filler in brake composite formulations. Its needle-like morphology helps improve mechanical reinforcement, dimensional stability, wear resistance, thermal performance, and structural integrity of friction materials.
Why Wollastonite is preferred across demanding industrial formulations.
Grade listed for Brake Composites applications.
Wollastonite supports a broad range of industrial processes and finished-product requirements.

Important information about Wollastonite, grades and applications.
Its acicular particle structure provides reinforcement and can help improve mechanical strength, dimensional stability, and wear performance.
Unlike more equiaxed fillers, wollastonite has a needle-like morphology that can provide additional reinforcing effects within the composite matrix.
Yes. When appropriately formulated, it can support controlled wear and increased structural durability.
Wollastonite offers good thermal stability, making it suitable for friction materials exposed to elevated operating temperatures.
It is suitable for disc pads, brake linings, railway friction materials, clutch facings, and industrial friction products.
Aspect ratio, particle size, purity, surface characteristics, and compatibility with the resin system should be considered.
