Zinc Borate is widely used in PVC applications such as carpet, conveyor belt, wire and cable, and in Nylon, PE, PP etc engineering plastics of halogen free flame retardant systems based on Al(OH) 3 and Mg(OH) 3 , anti-corrossive pigment in intumescent coating and painting,ceramic glaze, milk glass, decorative paper etc fields.Zinc Borate is also used in wood composite as fungicide to prevent from decay fungi and subterranean termites . ZB2335 grade is the standard grade, its particle size is 3-5um which can meet most of applications of Zinc Borate.
Package and Storage:
Zinc borate packed in 25kg/bag,18MT/20''container
