WHY HUNTITE
More than a filler. A mineral with a function.
Huntite is a naturally occurring calcium-magnesium carbonate. AGL Mining supplies huntite powder from Türkiye to industrial customers looking to explore mineral additives in their formulations.
Its endothermic decomposition makes huntite relevant to halogen-free flame-retardant systems, while its fine particle size supports its role as a functional mineral filler.
A mineral additive for the development of flame-retardant compounds.
Explore a filler that also contributes flame-retardant function within a suitable formulation.
THE SCIENCE, SIMPLY
When heated, huntite decomposes endothermically. Its mineral chemistry brings a physical contribution to flame-retardant formulations.
Endothermic decomposition absorbs heat as the mineral breaks down.
Carbon dioxide released during decomposition helps dilute combustible gases.
The resulting oxide residue helps form a protective layer in the material.
A simplified explanation of the mineral’s action, not a timed test sequence. Final performance depends on the complete formulation.
APPLICATIONS
From polymer compounds to protective coatings, explore where a functional mineral additive could fit your next development.

Explore huntite as a halogen-free mineral flame-retardant additive and functional filler in polymer formulations.
Discuss your application
A mineral additive to evaluate in cable compounds where halogen-free flame-retardant formulations are being developed.
Discuss your applicationApplications are indicative. Suitability and loading levels should be confirmed in your own formulation trials. Images illustrate application areas and do not depict products made with AGL huntite.
