1,environmental halogen-free flame retardant
2,additive or substitute product of expensive flame retardant
3,good hot stabilit

Introduction:
Because of its big particle size in about 8um, ZB800 is mainly recommended to use in anti-corrosion, fungicide for wood preservation etc fields. Zinc Borate can protect from destroying organisms for wood composite materials in above-ground applications. It is used as an additive in the manufacturing of plastic wood material to control the growth of white and brown rot decay fungi. Zinc Borate also helps protect composite materials from damage caused by wood destroying insects, including subterranean termites such as Coptotermes formosanus.
ZB800 is used as flame retardant and smoke suppressant in some polymer system that needs big particle size or better flowability.

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