Decabromodiphenyl ethane, or for short, is a highly efficient brominated flame retardant. Taixing can provide various types of flame retardants, including this one. It boasts high thermal stability and flame retardant properties, and its molecular structure and chemical properties enhance the fire safety of polymers and plastics, making it a popular flame retardant choice in multiple industrial sectors.
DBDPE works through a gas-phase flame retardant mechanism. When it decomposes at high temperatures, bromine atoms are released and capture free radicals generated during combustion. Through this phenomenon, it can inhibit the rapid spread of the combustion reaction. Moreover, the decomposition process itself needs to absorb heat, which reduces the reaction rate of other combustible materials and the spread of fire.
And at the same time, during the pyrolysis process, the decomposition products of decabromodiphenyl ethane can react with the matrix material, promoting the carbonization process. The carbonized layer can isolate oxygen from the matrix material, thus providing solid-phase flame retardancy.
is added using a melt blending method. The entire addition process involves three main steps. First, pretreatment is necessary. We recommend pre-drying the DBDPE and polymer matrix to remove moisture and avoid defects in subsequent processing.
After drying, the DBDPE powder, polymer, and other necessary additives are pre-mixed in a high-speed mixer. This lays a solid foundation for uniform dispersion. Once everything is ready, melt blending and granulation can be carried out. We will not go into detail about this process. The final flame-retardant masterbatch can be directly used in various molding processes.
Taixing's advice is to confirm the formula with us before production. We will determine the amount to add based on the type of polymer, the target flame retardant rating, and the compatibility between the polymer and the flame retardant. We will pay close attention to both the formula and processing to achieve more efficient flame retardancy.
