Montmorillonite

Montmorillonite (MMT) is a layered phyllosilicate clay with high surface area and a 2:1 layered structure that makes it one of the most effective mineral charring agents for intumescent flame-retardant systems.

When incorporated at low loadings — typically 2–10 wt% — and properly intercalated or exfoliated, MMT creates a tortuous path that significantly slows gas diffusion and heat penetration during combustion, resulting in a more coherent and thermally resistant char layer.

Its platelet morphology provides additional mechanical reinforcement, improving tensile strength and modulus without the heavy loading penalties of conventional mineral fillers. This dual charring-and-reinforcement function makes MMT highly cost-effective.

Organically modified grades (OMMT) are available for polyolefin and styrenic systems; standard grades suit polar engineering resins such as PA, PBT, and epoxy.

Sourced from high-purity deposits and processed to consistent cation exchange capacity (CEC), ensuring predictable intercalation in both solvent and melt compounding processes.
