Phosphonitrilic chloride trimer Uses
Due to the active nature of the phosphorus-chlorine bond, chlorine can be easily substituted to form a series of phosphazene derivatives with special properties. It is an intermediate raw material for synthesizing various halogen-free flame retardants and high temperature resistant materials, such as phenoxyphosphazene, p-carboxyphenoxyphosphazene, polyaminophosphazene, alkoxyphosphazene and other flame retardants. Polyphosphazene elastomer material, etc. Formally, for this reason, a series of phosphazene compounds can be produced.
