Phosphorus flame retardant

Phosphorus flame retardants are mostly liquid, mainly used in PU, PVC and other plastics. Small molecule phosphorus flame retardant main drawback is volatile, heat resistance is not high, is currently working to develop high molecular weight compounds and oligomers, of a halogenated phosphate, containing phosphorus, bromine, chlorine, with

A flame retardant and plasticized, crosslinked flame retardant and phosphorus flame retardant multi-functional development is another major aspect, the flame retardant plasticizer, especially at low temperatures is mainly used for the plasticization of PVC products, such as domestic production dicumyl phosphate. Some of the crosslinking agent is a flame retardant

The phosphorus-containing reactive polyols, not only as the PU reactive flame retardant, but also with the brominated plastic flame retardant and used epoxy resin, can significantly reduce the amount of brominated flame retardants. Phosphorus flame retardants in the future but also to the development of low toxicity, not only solved the drug product itself

Sex, but also consider the toxicity of the combustion products of decomposition and waste pollution problems, or even to consider the production, sales, storage and transportation process of toxicity problems.
