Introduction:
Zinc Borate is environmental protection non-halogen flame retardants, According to the difference of composition (XZnO.YB2O3.ZH2O), FB flame retardant has more than ten varieties. 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.
Product Applications:
1. Zinc Borate can be used as a kind of multi-functional synergistic additive of Antimony oxide and other halogen flame retardant ,can improve the nature of flame retardant effectively, to reduce the smoke produced when combustion, and can adjust rubber products chemical machinery, electricity and other aspects of performance.
2. As the partial or completely environmental protection substitute of containing halogen and other flame retardants , zinc borate is being directly applied to a wide range of plastics and rubber processing, such as PVC, PE, PP, enhance polyamide, PVC resin, polyphenylene ethylene, epoxy resin, polyester resin acid ethylene and natural rubber, styrene butadiene rubber, chloroprene rubber. It can also be applied to the production of paper, fiber fabric, decorative panels, floor leather, wallpaper, carpet, ceramic glaze, fungicides, and paint production in order to improve flame retardants performance.
3. Based on other natures, zinc borate, can also be used for anti-corrosion, far-infrared absorption, and timbers anti-pest and anti-bacteria handle and other fields.
Package: The main package is 25 kg / bag, 500 kilograms / tons of bags. It can also be customized a variety of packaging weight according to the clients requirement.
