Welcome to Imerys Performance Minerals


PVC Imerys talcs improve the mechanical properties and processing in PVC applications

Imerys talcs improve the mechanical properties of PVC enabling its use in a wider range of applications. 

Reinforcement agent

PVC is used for a wide range of end products such as flooring and extrusions, but its use is sometimes limited in applications requiring superior mechanical properties and heat resistance.

Due to their inherent lamellarity, Imerys talcs improve:

  • Coefficient of linear thermal expansion (CLTE)
  • Dimensional stability
  • Stiffness
  • Operating temperature

In tests, very fine talc outperforms other fillers such as chalk and chalk / talc blends. 

It can also be used in foamed PVC to increase the cell nucleation and improve the foamed material stiffness.
