The mechanisms of FR additives are as follows: -FR mechanism of condensed phase: It can promote the cross-linking and charring of polymer in the combustion process (promote dehydration, condensation, cyclization, cross-linking and increase charring residue), which belongs to the FR of condensed phase. -Gas phase FR mechanism: The added flame retardant can capture free radicals in the gas phase during the combustion process of materials, which generally belongs to the gas phase FR mechanism. -Interruption of heat exchange mechanism: the material cannot maintain the thermal decomposition temperature, and therefore can’t maintain the production of flammable gases, so that the combustion self-extinguishing.
- Fabric will be extinguished and won’t continue burn once leave the fire.
- Fabric still has FR effect after repeated washing.
- Non-halogen, no limited metals, no irritating odor during combustion
