Materials that do
a specific job
A filler is never just a filler, and an additive is never just a line on the recipe. Choose your industry to see the mineral grades and specialities we hold, and the producers behind them.

7 productsSame material, different specification
Calcium carbonate appears in nine of our eleven industries — but a coating grade, a PVC grade and a feed grade are three different products with three different tolerances. The same is true of every speciality we sell.
- Particle size distribution — top cut, d50 and fines content matched to your dispersion equipment and target rheology.
- Surface treatment — stearate-coated or untreated, chosen for compatibility with your binder system.
- Purity and colour — brightness, yellowness index and iron content where whiteness or glass melt behaviour matters.
- Functional performance — for specialities, the number that matters is viscosity build, wetting, foam knock-down or flame class, not the assay.
- Regulatory status — technical, food, feed or pharmaceutical grade, documented before you qualify.
Opacity, matting, rheology
Extenders, engineered aluminium silicates and cristobalite, plus thickeners, dispersants and defoamers for the same formulation.
Stiffness, flame class, cost
Treated GCC, calcined kaolin and talc alongside ATH and magnesium hydroxide for compound, masterbatch and cable.
Workability and water retention
Mineral aggregates and fillers with rheology modifiers and water-repellent additives for adhesives, renders and plasters.
Thermal stability
Fused and tabular alumina, mullite, cordierite, chamotte, zircon, high alumina cement and binder systems.
