  Use:Zinc borate is inorganic addition flame retardant. it has good hot stability, stops buring and vanishes smokings. It can replace antimonous oxide but also be used with other inorganic flame retardant. Widely used in rubber, plastic, wood, cable, coating, etc.Zinc borate,modified can completely replace zinc borate. It have the advantage of lower price, better effect stops buring and vanishes smokings.

  Package:Paper-plastic bag or plastic weaved bag, lined with PE bag and 25KG or 40KG weight.
