Introduction:
Zinc Borate is one environmental-friendly halogen-free flame retardant. There are some formulations of XZnO.YB2O3.ZH2O, in which Zinc Borate anhydrous is called ZB-23 (2ZnO.3B2O3). ZB700 is stable up to 600°C,so it can be used in polymer systems requiring very high processing temperatures. It can be added into extruders, calenders, or injection molding equipment.ZB700 is used as a flame retardant and smoke suppressant in some polymers, such as polyetherketone, polysulfone, fluoropolymer, polyester and nylon etc.

Package:
Zinc borate should be stored with very good seal, and transported as normal chemical goods.
Standard package is 25kg/bag,500kg/bag,and can design package according to order.
