High-purity Sb₂O₃ content (≥99.5%) ensuring consistent flame-retardant synergy with halogenated compounds.
Ultra-fine particle size distribution (D₅₀ ≤ 1.5 μm) for excellent dispersion in polymer matrices.
Low heavy metal impurities (Pb < 5 ppm, As < 3 ppm) meeting stringent RoHS and REACH compliance requirements.
Thermally stable up to 650 °C, minimizing decomposition during high-temperature processing.
Non-hygroscopic surface treatment enabling long-term storage stability and reduced agglomeration.
Polyvinyl chloride (PVC) cables and wire insulation.
Acrylonitrile-butadiene-styrene (ABS) housings for electronics and appliances.
Expanded polystyrene (EPS) and extruded polystyrene (XPS) thermal insulation boards.
Polypropylene (PP) automotive interior components.
Textile back-coatings and technical fabrics requiring flame resistance.
