Flame Retardants, Halogen

T3MB Bromine Antimony Composite Flame Retardant Masterbatch

T3MB is a bromine–antimony composite flame retardant masterbatch developed to outperform traditional ATO and bromine systems. It provides high flame-retardant efficiency, uniform dispersion, and improved processing stability in thermoplastics and elastomers. With a flame-retardant content of ≥80 percent and thermal stability above 300 °C, T3MB supports UL94 V-0 performance in multiple engineering polymer systems. Its fine particle size and clean pellet form make it suitable for high-efficiency flame-retardant formulations.
