There are a lot of flame grading standards, in general, the plastics industry in accordance with the standards of UL94, plastic flammability rating by HB, V-2 flame retardant wool, V-1 to V-0 incremental common with 1 / 8V0,1 / 16V0,1 / 32V0 (domestic often called 3.2V0,1.6V0,0.8V0), in order to increase the difficulty, depending on which specific V0 rating depending on the thickness of the spline. The classification of flame retardancy according to different standards, or different levels divided. Into the building fire standards: A1, A2, B, C, D retardant wool manufacturer, E, F in the standard method in Weifang wool flame retardants, partakers: M0, M1, M2, M3, M4 want You see what specific aspects of the flame retardant may be. Shandong Antai New Material Technology Co., Ltd. Main wool flame retardant wool manufacturers, welcomed the new and old customers to buy. Covering the role of wool flame retardants: In the combustible material after adding a flame retardant, flame retardants at high temperatures to form a glassy or stable foam cover, cut off oxygen, with insulation, oxygen, combustible gases outward to prevent escape the role of the flame retardant to achieve the purpose. Can produce a crosslinked structure more stable solid matter or carbonized layer such as organic phosphorus flame retardant heat. Carbide layer is formed on the one hand can prevent further polymer pyrolysis, on the other hand can prevent heat from entering the inside of the gas phase decomposition of participation in the combustion process.
