Phosphorus-based flame retardants give various complex reactions in the event of a fire, but mainly work by solid phase pyrolysis (decomposition) of polymers, forming a carbon-rich, dense char on the surface of the polymer. As a result, oxygen has less access to the fuel and delays the fire. Because this product is a polymer, it does not bloom, making it more effective. It "binds" with the polymers such as PET, PBT, PLA, PC and TPU.
These phosphonates are hygroscopic materials therefore, it is important that the material is thoroughly dried prior to melt processing (<50 – 200 ppm moisture).
These flame-retardants are considered non-hazardous materials when handled in accordance with standard industrial hygiene practices PROPERTIES
