Introduction:ÂÂ
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****5, 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.ÂÂ

Product
Applications:ÂÂ
 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.ÂÂ
