Firebrake 500 is an anhydrous zinc borate that’s designed to stand up to high-temperature polymer processes. Polymer manufactures gain multiple benefits from Firebrake flame retardants—supported by technical expertise from U.S. Borax.
Not all borate products provide the same amount of useable boron. For applications that require consistency in formulation as well as practical economy, refined borates provide a better value than raw mineral borates.
