How To Test The Flame Retardant Effect Of Flame Retardant Fabrics? At present, the flame retardant effect test methods of flame retardant fabrics mainly include the following: Limiting oxygen index (LOI) method: LOI refers to the minimum oxygen concentration required to maintain the candle-like burning of the fabric when combustion occurs in a mixture of oxygen and nitrogen. The larger the limiting oxygen index, the better the flame retardant …

Why is HBCD Banned? Beginning in the 1990s, the additive brominated flame retardant HBCD has gradually been used in building insulation materials throughout the world, and its usage has gradually increased. However, international studies have found that HBCD itself is toxic and has the potential for long-distance environmental migration, which can affect the regional and global environment through …

Knowledge Of The Use Of Flame Retardants In general, the flame retardant mechanisms of bromine and chlorine systems are similar. At high temperature, the carbon-halogen bond in halogen-based flame retardants will be damaged, releasing halogen free radicals, which can effectively capture free active free radicals generated by thermal degradation of polymer materials, and can effectively reduce the concentration of free …
