Flame Retardant Bentonite for Advanced Fire-Safety FormulationsFlame Retardant Bentonite is a functional layered mineral additive based on high-quality montmorillonite. It is used in combination with the primary flame-retardant package—not as a standalone replacement—to support the overall fire-performance, rheology and stability of formulated systems.
Its plate-like mineral structure can contribute to the formation of a compact inorganic barrier during thermal exposure. In properly designed systems, this barrier can help slow heat and mass transfer. Performance must always be verified in the customer’s complete formulation and according to the applicable fire-test standard.
