Firebrake 500 Dehydrated zinc borate Borax Flame retardant / Fire retardant >> Boron based Amide Resins Fluoropolymer Compound Polyester End-use applications: coatings Firebrake 500 fire retardant is a dehydrated zinc borate with multifunctional applications in a variety of polymers. Since it contains no water of hydration, it is stable up to 600 °C. It can therefore be used in polymer systems requiring very high processing temperatures. It can be fed to extruders, calenders, or injection molding equipment in the same way as other solid polymer additives. Firebrake 500 can be used as a flame retardant and smoke suppressant in a variety of polymers including polyetherketone, polysulfone, fluoropolymer, polyester and nylon. The very significant beneficial effect of Firebrake 500 on rate of heat release is of special interest where this factor is important, as in aircraft applications. Dehydrated zinc borate. Used as a flame retardant and smoke suppressant in coatings. Contains no water of hydration. Offers very significant beneficial effect on rate of heat release. Suits for systems requiring very high processing temperatures. Gives compatibility with polyetherketone, polysulfone, fluoropolymer, polyester and nylon.
