Zinc Borate is environmental protection non-halogen flame retardants, Through SGS testing, zinc borate is environmental protection type non-halogen flame retardants. Zinc Borate can be used as a fire retardant in PVC, Polyolefins, Elastomers, Polyamides, Epoxy resins. In halogen-containing systems, ZB is used in conjunction with antimony oxide, while in halogen-free systems; it is normally used in conjunction with alumina trihydrate, magnesium hydroxide, or red phosphorus. In some particular application Zinc Borate can be used alone. The most commonly used variety is this product-3.5 water zinc, also know ZB-2335, flame retardants. This product is non-toxic, low-water-soluble, high heat stability, small particle size, proportion small proportion, good dispersion characteristics, as highly effective flame retardants is widely used in plastics, rubber, paint and other fields.
