Fillers grade
Overview
Hydrous and calcined kaolin as a functional extender: TiO₂ spacing and opacity in paint, reinforcement in rubber, electrical properties in cable compounds. Calcined grades offer higher whiteness and oil absorption.
- Hydrous and calcined options
- High whiteness to extend TiO₂ in paint
- Controlled oil absorption and D50
- Low grit for smooth films and compounds
