Our wollastonite’s reinforcing needle-like structure, its low hydroabsorptivity, thermal stability and conductivity, low resin demand and chemical purity make it an ideal additive to polymer formulations. It is used in an array of thermoset, thermoplastic and elastomeric applications including:

  • nylon 6 and 66/high temperature PA compounds
  • polyurethane
  • elastomers

NYCO’s suite of chemically surface modified products meets the demand for improved composite properties. Coupling agents like organo silanes and other additives used with our wollastonite improves the interface between the filler/reinforcement and the polymer. Benefits of Wollastonite in Plastics Whether you’re designing a new composite, or updating an existing formulation, NYCO’s wollastonite products offer a significant advantage over other fillers and reinforcements.

Our wollastonite:

  • improves dimensional stability
  • increases flexural modulus
  • improves heat distortion temperature
  • improves strength and stiffness properties
  • improves mar, scratch and gouge resistance
  • reduces shrinkage
  • has a lower coefficient of linear thermal expansion (CLTE) – no gap
  • offers heat sag resistance and improved heat aging
  • is e-coat compatible with a Class A surface appearance
  • provides excellent balance in impact and stiffness
  • offers knit line reduction

And when compared to other fillers and reinforcements, our products also yield:

  • cost savings
  • higher loadings
  • improved product flow, faster mould cycles
  • product uniformity
  • lower initial viscosity
  • scrap reduction
