Welcome to Imerys Performance Minerals


Foaming Imerys minerals for uniform cell size and distribution in polymeric foam

Imerys minerals make superior nucleating agents for polyolefin-based foam composites used to produce lightweight materials with improved stiffness at lower densities.

Calcium carbonates
Imerys ground calcium carbonates (GCC), such as our PolCarb® and ImerCarb® grades are very cost-effective foaming agents for PVC

Precipitated calcium carbonates (PCC) such as our Socal® and Winnofil® grades are excellent foam nucleation additives in expanded polystyrene (EPS).

We offer a full range of custom formulation and technical and process support services to help you match the right mineral grade to your application requirement.
