NYCO's wollastonite is the next generation of engineered fibres for friction materials.

Our products are commonly used as reinforcing fibres and fillers in friction formulations. Wollastonite's synergistic effect with other fibres also makes it an excellent processing aide.

Whether used as a reinforcing additive or as partial/full replacement of asbestos, synthetic materials and chopped or milled glass fibres, our wollastonite can be found in a variety of applications:

  • semi-metallic and non-asbestos organic (NAO) formulations for truck blocks, drum linings, disc pads, clutch facings and shims
  • OEM and aftermarket built passenger cars/light trucks and heavy-duty trucks
  • heavy equipment, industrial and off-road vehicle applications
  • friction papers

Wollastonite is a natural reinforcement choice for making better friction products. Friction formulations using our products benefit through:

  • reduced cost: raw material and unit cost (density)
  • improved friction stability
  • reduction or elimination of cracking
  • noise reduction
  • improved fade and recovery
  • improved physical and mechanical properties
  • improved pre-form strength
  • non-hazardous ingredient for asbestos replacement
  • reduction in airborne fibre (when partially replacing asbestos)
