Flame retardant DBDPE

The flame retardant DBDPE produced by Taixing is an efficient bromine based flame retardant without ether bond structure, which fundamentally eliminates the generation of highly toxic substances such as dioxins and furans during thermal decomposition. At the same time, with ultra-high bromine content and excellent thermal stability, it is widely used in fields such as electronics and electrical engineering, new energy vehicles, and building materials.

Core strengths

1. Safety design

-No toxic decomposition products: Ethane bridge bonds are used instead of traditional ether bond structures. During thermal decomposition, only hydrogen bromide and a dense inert carbon layer are generated, 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 ≤ 48, far better than the industry average level.

-Low bioaccumulation and environmental friendliness: chemically stable and not easily enriched in living organisms, no harmful substances migrate or infiltrate during waste disposal, in line with the principles of green chemistry lifecycle management, helping customers obtain dual certification for carbon footprint and green products.

2. Ultra high flame retardant efficiency

-Bromine content ≥ 83%: The flame retardant efficiency per unit mass is increased by 12% compared to traditional bromine based flame retardants. It quickly captures combustion free radicals in the gas phase to interrupt chain reactions, 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 of effectively suppressing flame spread. Paired with 3% -5% antimony trioxide synergist, PP and ABS substrates with a thickness of 1.6mm can easily meet UL 94 V-0 flame retardant standards.

-Ultimate thermal stability: 1% thermal weight loss temperature ≥ 330 ℃, maximum decomposition temperature ≥ 425 ℃, processing temperature window width up to 190-245 ℃, suitable for various processing techniques such as extrusion, injection molding, blow molding, and compression molding. There is no decomposition, yellowing, or gas evolution during high-temperature processing, and it does not affect the appearance accuracy and mechanical properties of the product.

-High temperature specific version customization: For high-temperature engineering plastics such as nylon, PBT, PET, etc., we have launched a high-temperature stable DBDPE. The 1% thermal weight loss temperature has been increased to above 350 ℃, and it can withstand processing temperatures above 300 ℃, meeting the flame retardant modification needs of high-end engineering plastics.
