zinc borate flame retardant is used as an environmentally-friendly additive halogen- free flame retardant and smoke suppressant in various polymer systems in engineering plastics, rubber based compounds such as hose, conveyor belt, coated canvas, FRP, wire and cable, electrical components, coating and painting, etc. zinc borate flame retardant can be packed in Net weight 25kg/bag, Compound paper-plastic bag
Zinc borate flame retardant appears in the form of white triclinic crystals or amorphous powder, and this appearance characteristic ensures that it does not significantly affect the original color and appearance of the material when integrated into various material systems. Slightly soluble in water, insoluble in hydrochloric acid in crystal form, while amorphous powder is soluble in hydrochloric acid. This solubility characteristic can accurately play its role in specific material processing and application scenarios.
Zzinc borate flame retardant Storage and Attention :Keep in dry, room temperature and moisture proof condition, preventing the heating.
