DBDPE Powder

DBDPE powder, a brominated flame retardant optimized by molecular structure. It is not a traditional substitute for decabromodiphenyl ether (Deca BDE), but a fundamentally more advanced and safer solution. The DBDPE powder produced by Taixing completely avoids the risk of dioxin and furan formation through innovative ethane bridging molecular structure, and is specially developed to meet the composite requirements of safety, performance, and environmental protection for high-end electronic and electrical, intelligent transportation, and sustainable building materials.

Core strengths

1. Precise micrometer particle size control, ultimate dispersion performance

-Adopting an integrated process of supersonic airflow crushing and graded purification, the average particle size D50 is precisely controlled between 1.5-3.0 μ m (customizable for a full range of particle sizes from 0.8-5.0 μ m), with a particle size distribution span of ≤ 0.8 μ m and no large particle impurities or aggregates

-The angle of repose of the powder is ≤ 28 °, with excellent flowability. It can be quickly and uniformly dispersed during high-speed stirring, twin-screw extrusion and other processing processes, without the need for additional dispersants to achieve a high gloss product effect without white spots or pockmarks in the substrate

-Surface modification with fatty acid salt composite improves interfacial compatibility with polymer matrices such as PP, PE, ABS, HIPS by 40%, completely solving the problem of flame retardant performance fluctuations caused by uneven dispersion of traditional DBDPE powders

2. Efficient flame retardant and high thermal stability, suitable for diverse processing scenarios

-Bromine content ≥ 82.5%, leading the industry in flame retardant efficiency per unit mass, rapidly suppressing flame spread under the dual action of gas phase and condensed phase. Combined with 3% -5% antimony trioxide synergist, it can easily achieve UL 94 V-0 flame retardant standard for 1.6mm thick substrates

-1% thermal weight loss temperature ≥ 325 ℃, maximum decomposition temperature ≥ 420 ℃, processing temperature window width up to 190-240 ℃, suitable for various processes such as extrusion, injection molding, blow molding, and compression molding. There is no decomposition, yellowing, or gas release during high-temperature processing

-The thermal stability has been strengthened by special processes, and a high-temperature specific DBDPE powder has been launched. The decomposition temperature has been raised to above 340 ℃, which can meet the high-temperature processing needs of engineering plastics such as nylon, PBT, PET, etc

3. Full dimensional environmental compliance, non-toxic risks and hidden dangers

-The molecular structure replaces ether bonds with ethane bridge bonds, and does not produce highly toxic substances such as dioxins and furans during thermal decomposition. The toxicity level of combustion smoke meets the EU EN 13501-1:2024 low smoke toxicity standard, and the smoke density level (SDR) is ≤ 50

-Fully passed the EU REACH regulation's 250 SVHC list certification, RoHS 2.0 directive, TSCA in the United States, Prop 65 in California, GB/T 2408-2021 in China and other global mainstream standards, with a bioaccumulation factor (BCF) ≤ 800 and no risk of vPvB (high persistence, high bioaccumulation)

-The product production process adopts a closed-loop water circulation and waste heat recovery system, reducing dust emissions by 90% and complying with ISO 14001 environmental management system certification. It is green and environmentally friendly throughout the entire lifecycle

4. Low addition amount and low performance loss, ensuring the original characteristics of the substrate

-Under the same flame retardant requirements, the addition amount is reduced by 10% -15% compared to traditional coarse powder DBDPE, effectively reducing material density and formulation costs, while minimizing the impact on the mechanical properties of the substrate

-The influence rate of DBDPE powder on polymer tensile strength and impact toughness is ≤ 6%, far below the industry average. Modified DBDPE powder can achieve a mechanical property retention rate of ≥ 94%, without affecting the weather resistance and dielectric properties of the product
