Antimony Trioxide Micron Powder (Sb2O3, 99.9+%, 1 micron)

Description

Antimony Trioxide Micron Powder (Sb2O3, 99.9+%, 1 micron)

Antimony Trioxide Micron Powder is a high-purity (99.9+% Sb₂O₃) inorganic material with a controlled particle size of approximately 1 micron, developed for demanding industrial applications. It functions primarily as a synergist in flame-retardant systems, enhancing the fire resistance of polymer and composite materials.

Thanks to its fine particle size, the product offers high surface area, uniform dispersion, and efficient interaction within polymer matrices. This enables stable and reproducible performance even at relatively low loadings. The high purity level supports process reliability and consistent end-product quality.

Antimony Trioxide is a well-established functional material widely used in plastics, elastomers, coatings, and advanced material systems, including applications within the defense industry, chemical processing, and materials engineering.
