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.

Use of zinc borate:

1. It can be used in the production of paper, fibre fabric, decorative board, floor leather, wallpaper, carpet, ceramic glaze, bactericide and paint to improve the flame retardant performance.

2. As a partial or completely environmentally friendly substitute for halogen-containing flame retardants, it 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.

3. As a multi-functional synergistic additive of antimony oxide or other halogen flame retardants, it can effectively improve flame retardancy, reduce smoke generation during combustion, and adjust the chemical, mechanical and electrical properties of rubber and plastic products.

4. It can also be used in the fields of anti-corrosion, far infrared absorption, wood insect and bacteriological treatment, etc.

Zinc borate is an environmentally friendly non-halogen flame retardant. It is non-toxic, low water solubility, high thermal stability, small particle size, small specific gravity and good dispersibility. As a highly effective flame retardant, zinc borate is widely used in plastics, rubber, coatings and other fields.
