  Applications:
  Zinc Borate is one multi-functional synergistic flame retardant with Antimony Oxide etc additives in polymers to improve flame retardant performance, it can reduce smoke evolution and adjust the balance of flame retardant properties versus mechanical, electrical and other properties.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 & Transportation:
  Standard package is 25kg/bag,40bags/pallet,18MT/20''container.
  Zinc borate should be stored with very good seal, and transported as normal chemical goods.
