Foaming Imerys talcs for improved cell size and distribution in polymeric foam
Imerys micro-lamellar talcs make superior nucleating agents for polyolefin-based foam composites used to produce lightweight materials with improved stiffness at lower densities.
The high surface area of these micro-lamellar talcs promotes the nucleation of uniform / narrow gas bubbles during foaming process increasing the number of foam cells and making cell distribution and growth more consistent.
Imerys talcs provide:
- A significant increase in cell density
- Fine and regular cell size
- Improved stiffness at lower densities
- Optimized lightweight materials
PP cell density increases with talc loading
We particularly recommend our Mistrocell® range of micro-lamellar talc products or our surface treated Mistron® ZSC micro-lamellar talc for nucleating polyolefins, PS, PVC and polyurethane foams.
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
