DBDPE

DBDPE produced by Taixing has become a benchmark product for replacing traditional polybrominated diphenyl ethers (PBDEs) through innovative molecular structure design and full industry chain process optimization. This highly efficient bromine based flame retardant without ether bond structure fundamentally eliminates the generation of highly toxic substances such as dioxins and furans during thermal decomposition. At the same time, with its ultra-high bromine content and excellent thermal stability, it provides a solution that meets both flame retardancy and compliance safety standards for industries such as electronics, new energy vehicles, and building materials, helping multinational enterprises easily break through global market access barriers.

Core strengths

1. epoch-making molecular design

-No toxic decomposition products: Ethane bridge bonds are used instead of traditional ether bond structures. During thermal decomposition, only hydrogen bromide and an inert carbon layer are produced, without producing highly toxic substances such as dioxins and furans. The toxicity of combustion smoke meets the EU EN 13501-1:2024 low smoke toxicity standard, and the smoke density level (SDR) is ≤ 50.

-Low bioaccumulation: chemically stable and not easily enriched in living organisms, no harmful substances migrate during waste disposal, in line with the principles of green chemistry full life cycle management, helping customers obtain carbon footprint certification for their products.

2. Ultra high flame retardant efficiency, suitable for scene applications

-Bromine content ≥ 82.5%: The flame retardant efficiency per unit mass far exceeds similar products. It quickly captures combustion free radicals in the gas phase and promotes the formation of a dense carbon layer in the condensed phase, with a dual effect of suppressing flame spread. Combined with 3% -5% antimony trioxide synergist, it can easily achieve UL 94 V-0 standard for 1.6mm thick PP and ABS substrates.

-Ultimate thermal stability: 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, and it does not affect the appearance and performance of the product.

-High temperature specific version available: For engineering plastics such as nylon, PBT, PET, etc., a high-temperature stable DBDPE is launched, with a 1% thermal weight loss temperature increased to above 340 ℃, meeting the processing temperature requirements above 300 ℃.

3. Excellent material compatibility, minimizing performance loss

-Broad spectrum polymer compatibility: Perfectly compatible with general plastics such as PP, PE, ABS, HIPS, XPS, as well as engineering plastics such as nylon, PBT, PET, and can also be used for flame retardant modification of materials such as rubber, coatings, textiles, etc.

-Particle size and surface modification optimization: average particle size D50 ≤ 2.5 μ m (customizable 0.8-5.0 μ m), excellent powder flowability (angle of repose ≤ 28 °); The surface is treated with fatty acid salt composite modification, which improves the compatibility with the polymer matrix interface by 40%, disperses evenly without agglomeration, and does not produce appearance defects such as white spots and pockmarks.

-Low mechanical performance impact: Under the same flame retardant requirements, the addition amount is reduced by 10% -15% compared to traditional bromine based flame retardants. The impact rate on the tensile strength and impact toughness of the substrate is ≤ 6%, and the mechanical property retention rate is ≥ 94%. It does not affect the weather resistance and dielectric properties of the product.

4. Green production technology

-Adopting a closed-loop production system, water consumption is reduced by 50% and energy consumption is reduced by 35% during the production process. Wastewater and exhaust emissions meet the highest international environmental standards and have passed ISO 14001 environmental management system certification.

-The powder processing process adopts negative pressure dust removal technology, reducing dust emissions by 95%. The dust concentration in the production workshop is much lower than the occupational health and safety standards, ensuring the health of production personnel.
