zinc borate is an environment-protecting non halogen flame retardants, according to the different (XZnO composed YB2O3. J ZH2O), FB flame retardants ten several varieties. The most commonly used varieties for this product - 3.5 water zinc borate, say again ZB - 2335 flame retardants. This product is non-toxic, low water-soluble, high thermal stability, particle size is small, small proportion, good dispersion characteristics, such as a kind of high-efficient flame retardants are widely used in plastic, rubber, coating etc.

Application:
1. Zinc borate as antimony oxide or other halogen flame retardant additives, multi-function efficiency can be effectively improved flame-retardant performance and reduce combustion smoke of generation, and can adjust xiangsu products
machinery, electrical chemical properties such as.2. As the degumming halogen such as flame retardant partial or complete environmental alternatives,
zinc borate is being widely applied directly in plastic and rubber processing, such as PVC, PE, PP,
enhance polyamide, polyvinyl chloride (PVC) fat, polystyrene polyester, epoxy resin, acid and ethylene resin,
styrene butadiene rubber natural rubber, neoprene etc. Can also be applied to paper, fiber fabric, decorative,
DeBanGe, wallpaper, carpet, ceramics glost, fungicide, coating production, in order to improve the flame retardant properties.
3. The other properties based on zinc borate, it can also be used in antisepsis,
far infrared ray absorbing, wood anti-insect germ-proof processing, etc.

Application:
Because of its big particle size in about 8um, ZB800 is mainly recommended to use in anti-corrosion, fungicide for wood preservation etc fields. Zinc Borate can protect from destroying
organisms for wood composite materials in aboveground applications.
It is used as an additive in the manufacturing of plastic wood material to control the growth of
white and brown rot decay fungi.
Zinc Borate also helps protect composite materials from damage caused by wood destroying insects,
including subterranean termites such as Coptotermes formosanus.ZB800 is used as flame retardant and smoke suppressant in some polymer system that needs big particle size or better flowability.
