3Zinc borate hydrate


Implementation criteria: HG/T4827-2015




Introduction:


Zinc borate is an environmentally friendly non-halogen flame retardant. According to its composition (XZnO.YB2O3.ZH2O), there are more than ten kinds of FB flame retardants. The most commonly used product is zinc borate 3.5 water, also known as ZB-2335 flame retardant. The product is non-toxic, low water solubility, high thermal stability, small particle size, small specific gravity, good dispersibility and other characteristics. As a high-efficiency flame retardant, it is widely used in plastics, rubber, paint and other fields.




Product applications:


1. Zinc borate can be used as a multi-functional synergistic additive of antimony oxide or other halogen flame retardants, which can effectively improve flame retardancy, reduce smoke generation during combustion, and adjust the chemical, mechanical and electrical properties of rubber and plastic products.

2. Zinc borate, as a partial or completely environmentally friendly substitute for halogen-containing flame retardants, is widely used in the processing of plastics and rubber, such as PVC, PE, PP, reinforced polyamide, polychlorinated resin, polystyrene, epoxy resin, polyvinyl ester resin and natural rubber, styrene butadiene rubber, chloroprene rubber, etc. It can also be used in the production of paper, fibre fabric, decorative board, floor leather, wallpaper, carpet, ceramic glaze, fungicides and coatings to improve the flame retardancy.

3. Based on other properties of zinc borate, it can also be used in anti-corrosion, far-infrared absorption, wood insect control and bacterial treatment and other fields.
