Welcome to Imerys Performance Minerals

Wood plastic composites

Wood plastic composites Imerys talcs improve the structural integrity of WPCs

Lamellar Imerys talcs make cost-effective processing aids in PP and PE-based plastic WPCs widening the processing window, reducing moisture-related problems and improving the structural integrity of the final WPC product.

Imerys talc

Used in PP and PE-based plastic WPCs, Imerys talc:

  • Lowers compound viscosity, increasing extrusion speed while maintaining good surface appearance
  • Increases modulus of rupture, modulus of elasticity and HDT
  • Reduces water absorption and warpage
  • Improves dimensional stability in terms of shrinkage, warpage and isotropy
  • Reduces creep and elastic recovery performance
  • Improves rigidity after water soak and reduces swell in water

We particularly recommend our 40µm top-cut talcs, coarse JetFil®, Luzenac and Steamic® products  for WPCs.
