Introduction: 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.
Packing:
This product can be packed, transported and stored according to conventional chemical. If the customer to specific indexes have special requirements, can according to requirements of products Main packing for 25 kg/bag, 500 kg/ton bag, can also according to customer requirements of various weight packing
