2.excellent quality and reasonable price
Introduction:
Because of its big particle size in
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.
