Flame Retardant Filler ATO

The flame retardant filler ATO, CAS No. 1309-64-4, developed and produced by Taixing, is a product that can actively optimize the performance of the entire flame retardant system through extreme control of its purity, particle size distribution, crystal structure, and surface chemistry. It not only ensures excellent halogen antimony gas phase synergy, but also stabilizes the formulation system, broadens the processing window, and enhances the overall reliability of the final product. Breakthrough the industry pain point of poor compatibility between traditional ATO and organic matrix, and achieve dual optimization of flame retardant efficiency and processing performance.

Core strengths

1. Ultra pure quality and precise functional control

-The main content of Sb₂O₃ is ≥ 99.9%, the doping amount of SnO ₂ is precisely controlled at 8% -12%, and the key impurity As₂O₃ is ≤ 0.02% PbO≤0.03%， Far superior to industry standards, eliminating the risk of harmful substance migration

-The average particle size can be customized to 50-200nm (conventional 80-120nm), with a specific surface area of 40-70m ²/g. The proportion of cubic crystal structure is ≥ 95%, and the dispersibility is excellent, which does not affect the transparency and mechanical strength of the substrate

-Density of 5.2g/cm ³, melting point of 656 ℃, outstanding thermal stability, able to withstand high processing temperatures of polymer materials above 300 ℃ without decomposition or weight loss, suitable for various processes such as extrusion, injection molding, and casting

-Adopting vacuum freeze-drying technology, with a moisture content of ≤ 0.15%, there is no risk of clumping during long-term storage, and the flowability is 30% better than ordinary ATO products

2. Innovative modified technologies enhance collaborative efficiency

-Adopting a dual coating treatment of gamma glycidoxypropyltrimethoxysilane (KH-560) and phosphorus nitrogen composite modifier, an organic functional layer is formed on the surface of the particles through chemical bonding. The compatibility with polymers such as PP, PVC, PET is improved by 50%, completely solving the problem of agglomeration

-Strong synergistic effect with halogen-free phosphorus and nitrogen flame retardants, rapidly generating antimony halide gas-phase flame retardant layer and dense carbon layer during combustion, while releasing inert gas to dilute combustible gas. The flame retardant level can be upgraded from V2 to V0, and the limit oxygen index (LOI) is ≥ 35

-Combining smoke suppression and anti-static functions, the smoke density grade (SDR) during combustion is ≤ 60, and the electrical resistivity is controlled at 10 ⁶ -10 ⁸Ω· cm, which can reduce the use of additional anti-static additives and lower the formulation cost

-Under the same flame retardant requirements, the addition amount is reduced by 20% -30% compared to ordinary ATO, effectively reducing material density without affecting the tensile strength and impact toughness of the substrate

Frequently Asked Questions

Q1: What is the differentiation core of flame-retardant filler ATO compared to other high-purity ATO in the market?

A1: Differentiation lies in "systematic design thinking". Many high-purity ATOs only focus on chemical purity itself. The behavior of flame-retardant filler ATO in the entire polymer formulation system was considered from the beginning of its design: how to disperse it? How to interact with other components? Is it stable in long-term hot, light, and humid environments? Will it migrate? We have systematically solved these problems through the combined control of surface engineering, particle size distribution, and impurity mass spectrometry, transforming it from a "pure chemical" to a "ready to use formula optimization component".

The flame-retardant filler ATO aims to help customers achieve their goals in the most efficient, stable, and reliable way in areas where halogen antimony synergy is still needed, maximizing the value of classic technology.
