PU RAW MATERIALS>> ADDITIVES>> FLAME RETARDANT
Non-harmful flame retardants with no additional cost

Synthetic materials made from organic polymers usually burn very well due to their high carbon content; when turned into foams, they ignite even more easily -- and, depending on their chemical compositions, they produce toxic gases such as hydrogen cyanide or carbon monoxide. For this reason, polyurethane foams and other similar products have to be...
