white triclinic crystalline or amorphous powder, slightly soluble in water, crystals do not dissolve in hydrochloric acid, the amorphous powder dissolved in hydrochloric acid. Zinc borate is mainly used as the inorganic additives, non-toxic flame retardants for plastics, rubber, textile, paint and other industries. Can be used as antimony oxide or other halogenated flame retardants multi-functional synergistic additives, can effectively improve the flame retardancy and reduce the generation of smoke when burned, and you can adjust the chemical, mechanical, electrical and other aspects of the performance of rubber products. As part or completely environmentally friendly alternatives such as halogen-containing flame retardants are widely used in plastics and rubber processing directly, such as PVC, PE, PP, reinforced polyamide, polyvinyl chloride resin, polystyrene, epoxy resin, polyester and vinyl resins, natural rubber, styrene-butadiene rubber, chloroprene rubber. It can be applied to paper, fabric, decorative panels, floor coverings, wallpaper, carpet, ceramic glaze, fungicides, paint production, in order to improve the flame retardancy. It can also be used for corrosion protection, far-infrared absorption, timber pest biocontrol treatment and other fields.
