Post the halogen content
Its flame retardancy achieves V0 level and does not contain chromium, cadmium, lead, mercury and polybrominated diphenyl ethers. It will not affect the transparency and The initial physical characteristics. Flame retardant mechanism of PC sulfonate At present, the products commonly used in the industry are KSS, PPFBS, (STB). - Flame retardants generally flame retardant mechanism can be divided into: 1, gas-phase flame retardant, that is, inhibit the growth of the reaction in the combustion reaction of free radicals; 2, condensed phase flame retardant, that is, in the solid phase to terminate the heat of the polymer Decomposition and prevent the polymer from the release of combustible gases; 3, the interruption of heat exchange, the heat generated by the polymer away without feedback to the polymer, the polymer is no longer sustained decomposition. However, the flame retardant mechanism of sulfonate to PC is different from that described above. At present, most of them think that it can accelerate the carbonization rate of PC and promote the cross-linking of polymer molecules. PC Sulfonate Flame Retardant Application Status Sulfonate flame retardants commonly used in PCs are KSS, PPFBS, and STB. STB can also be used in combination with other flame retardants. When used alone, the halogen content of the system as a whole is less than 0.15% and in some regulations is classified as halogen-free material. It should be noted that the amount of more than 0.1%, not only can not improve the flame retardant properties of the material will also affect the transparency of PC.

Hi guys
"Halogen" means a "salt-producing". The point when halogens respond with metals they process an extensive variety for salts, including calcium fluoride, sodium chloride, silver bromide and potassium iodide.

hello to everyone
Halogens need aid 5 non-metallic components found for assembly VIIA of the periodic table. Fluorine, Chlorine, Bromine, Iodine, astatine. Halogen intends salt former furthermore mixes holding halogens would known as salts Halogens exist, toward space temperature, altogether. Three states of is concerned.
