High purity Decabromodiphenyl Ethane

The high-purity decabromodiphenyl ethane produced by Taixing has become a benchmark product for replacing traditional bromine based flame retardants through multi-stage distillation purification process and molecular structure stabilization technology. This highly efficient flame retardant with a purity of ≥ 99.5% is completely free of polybrominated diphenyl ether (PBDE) structure and harmful impurities. The thermal decomposition process does not release carcinogenic dioxins, fully meeting the highest global standards. It is suitable for high-end fields such as electronics and electrical, new energy vehicles, aerospace, etc., providing a triple guarantee of "high purity, high efficiency, and high compliance".

Core strengths

1. Over 99.5% high-purity quality

-Adopting a two-stage purification process of "melt crystallization+vacuum distillation", the product purity is stable at ≥ 99.5%, with a maximum of 99.8%. The content of key impurities (such as polybrominated biphenyls, free bromine, heavy metals) is controlled within 5ppm, far exceeding the industry's conventional standards.

-No residual catalyst and organic solvent, avoiding the negative impact of impurities on the dielectric and mechanical properties of the substrate, suitable for scenarios with strict purity requirements such as semiconductor packaging materials and high-frequency communication components.

-The powder has a uniform and pure white color, with a whiteness of ≥ 98. When added to transparent plastics and high-end coating systems, it does not affect the appearance transparency and surface glossiness of the product.

2. Safety design

-Ethane bridge bonds replace traditional ether bond structures, generating only hydrogen bromide and a dense inert carbon layer during thermal decomposition, without any release of highly toxic substances such as dioxins and furans. The toxicity of combustion smoke reaches the highest safety level of EU EN 13501-1:2024, and the smoke density level (SDR) is ≤ 45.

-The Bioaccumulation Factor (BCF) is ≤ 500, far below the international safety threshold. After disposal, it can be processed through environmentally friendly recycling processes, with no environmental residual risks, helping customers obtain green product certification for their products.

3. Ultra high flame retardant efficiency, suitable for various high-temperature processing scenarios

-The bromine content is ≥ 83.5%, and the flame retardant efficiency per unit mass is 15% higher than that of ordinary DBDPE. It quickly captures combustion free radicals in the gas phase to interrupt the chain reaction, promotes the formation of a dense carbon layer on the substrate in the condensed phase to block oxygen and heat transfer, and has a dual effect to effectively suppress flame spread.

-The 1% thermal weight loss temperature is ≥ 335 ℃, the maximum decomposition temperature is ≥ 430 ℃, and the processing temperature window is wide up to 200-250 ℃. It is suitable for various processes such as extrusion, injection molding, compression molding, and hot melt. Even in the processing environment of high-temperature engineering plastics such as nylon, PBT, PET, there are no decomposition, yellowing, or gas release problems.

-Excellent synergy with synergists such as antimony trioxide and zinc borate. When combined with 3% -4% antimony trioxide, PP and ABS substrates with a thickness of 1.6mm can easily meet UL 94 V-0 flame retardant standards, with a 15% -20% reduction in addition compared to ordinary DBDPE.

4. Excellent material compatibility, minimizing performance loss

-By using the silane coupling agent KH-560 directional modification process, a hydrophilic and oleophobic organic functional layer is formed on the surface of the powder. The interface compatibility with polymer matrices such as PP, PE, ABS, and epoxy resin is improved by 50%, and the dispersion is uniform without aggregation, and no appearance defects such as white spots or pockmarks are produced.

-The impact on the mechanical properties of the substrate is extremely low. Under the same flame retardant requirements, the retention rate of tensile strength is ≥ 96%, and the retention rate of impact toughness is ≥ 95%, fully meeting the structural strength requirements of high-end products.

-Widely adaptable to various material systems such as general plastics, engineering plastics, rubber, coatings, textiles, etc., it can be directly applied without adjusting existing processing equipment.
