Fire retardants that are halogen-free but full of fire-stopping power. Flame retardants help to save lives by slowing down or stopping the spread of fire or reducing its intensity. Also called fire retardants, they are used in anything from phones and curtains to car seats and buildings.

At Tosaf, we have formulated a halogen free flame retardant for PE foam that meets all the necessary FR standards (V0, V1, B1, B2 and M2), and can be used for cross-linked and non-cross-linked PE foam.

Explore the rise of halogen-free flame retardants (HFFRs), addressing environmental concerns while highlighting challenges and innovations.

2008年1月1日 · The chapter first discusses the challenges from replacing halogen-containing flame retardants by halogen-free flame retardants. It then discusses how to overcome the possible low flame retardant efficiency, serious melt-dripping behaviors, deterioration in mechanical properties, and so on, which are caused by this replacement.

2019年4月5日 · Ammonium polyphosphate (APP) is a halogen-free flame retardant suitable for improving the fire performance of polyamides and polyurethane foam, as well as for polyolefins and epoxies. Moreover, it has a low cost and a good processability.

Halogenated flame and fire retardants release halogen radicals that disrupt free radicals in the vapor phase and shut down the combustion process. Halogenated flame retardants include bromine, chlorine, fluorine, and iodine compounds.

Halogens are the elements in group VII including fluorine, chlorine, bromine, iodine, and astatine. They can be used in flame retardants for electronic products to meet flammability standards.

2002年10月1日 · An overview of recent developments of the chemistry of halogen-free flame retardant polymers is presented in this paper. The polymers or reactive monomers that are inherently flamed retarding contain P, Si, B, N and other miscellaneous elements.

It summarizes the synthesis methods for various types of halogen-free FR polymers and their nanocomposites, and critically reviews their flame-retardant behavior, toxic-gas evolution during combustion, and inhibition methods.

variety of halogen-free flame retardants are available today, which allow compounders to optimize their formulations. Table presents an overview of typical technical properties which can be achieved with halogen-free flame retardants in different polymers and …
