What zinc borate does, and who buys it
HOFNIL-ZB is a versatile boron-based flame retardant for polymers, plastics and rubber compounds. It releases water at high temperatures, which helps suppress fire.
It is effective in PVC, polyolefins, elastomers, polyamides and epoxy resins.
As general background, zinc borate is commonly used as part of a flame retardant package rather than on its own, where it also helps with smoke suppression. The right level depends on the polymer and the rating you are aiming for, so tell us the polymer and the target and we will advise.
This is one of our standalone flame retardant additives. See also ammonium polyphosphate and melamine cyanurate.
