Our Product Range

Performance-grade bentonites, minerals, and absorbent materials — available in powders, granules, and pellets for engineering, environmental, and industrial use.

Supplying the Materials Behind the Projects That Matter

Since 1989, Macromin Kentish Minerals has supplied a focused range of bentonites, clays, and mineral-based products used across drilling, tunnelling, sealing, and industrial processing.

We offer powders, granules, and pellets tailored to critical applications — from directional drilling fluids and grout mixes, to absorbent minerals used in coatings, ceramics, and cat litter.

Our materials are sourced from quality-assured suppliers and are chosen for performance, consistency, and suitability to demanding environments.
