Firebrake 415 Zinc borate Borax Flame retardant / Fire retardant >> Boron based Amide Resins Vinyl End-use applications: coatings Firebrake 415 fire retardant is a unique proprietary* zinc borate compound with multifunctional applications in a variety of polymers. It has an unusually high dehydration onset temperature of >415 °C (780 °F). Therefore it can be used in polymer systems requiring very high processing temperatures. It is a white powder that can be fed to extruders, calenders, or injection molding equipment in the same way as other solid polymer additives. Firebrake 415 can be used as a flame retardant and smoke suppressant in a variety of polymers. It is particularly useful in systems such as nylon that require high processing temperatures, where enhanced thermal stability has been noted in some cases. Firebrake 415 is also an excellent smoke suppressant for systems such as flexible PVC. Zinc borate. Used as a flame retardant and smoke suppressant in coatings. Offers high dehydration onset temperature. Suits for systems requiring very high processing temperatures. Gives compatibility with nylon and flexible PVC.
