Zinc Borate

Zinc borate is an inorganic compound, a borate of zinc. It is a white crystalline or amorphous powder insoluble in water. Its toxicity is low. Its melting point is 980 °C.

ZINC BORATE

1. Overview?

It is an inorganic compound that exists in the form of white crystals or amorphous powder, insoluble in water, has low toxicity, melting point 980 °C.

It is an environmentally friendly halogen-free flame retardant, formula xZnO.yB2O3.zH2O, where zinc borate with 3,5 hydrate called ZB－2335 (2ZnO.3B2O33.5H2O) is the one used. most commonly used. It has possessed some excellent properties of non-toxicity, good thermal stability, fine particle size, low specific gravity….

Zinc borate, which delays the flame, allows the formation of a safe zone. In the event of a possible fire, it helps to keep the loss of life and property to a minimum, thus providing time for human intervention.

It is produced with borate does not pose a threat to human health, providing a longer and longer shelf life in application areas than chemical products. Chemical flame retardant products that are restricted from use in many countries by the European Union directive have been replaced with it.

2. Applications

Zinc borate is one of the eco-friendly and halogen-free flame retardants. It can be used as a multi-functional synthetic additive for other halogenated flame retardants, which can improve the effectiveness of flame retardants, reduce smoke generation during combustion, and can regulate the chemical, mechanical and electrical properties of rubber and plastic products.

It is used as a flame retardant in combination with other chemicals, including antioxins trioxide, magnesium hydroxide, alumina trihydrate, and some bromine flame retardants.

Zinc Borate partially or completely replaces halogen-containing flame retardants, it is widely used in plastic and rubber processing, such as PVC, PE, PP, polyamide, polyurethane, polystyrene, epoxy resin, vinyl vinyl , styrene butadiene rubber, neoprene and the like.

It can be used in the production of paper, textiles, decorative panels, flooring, wallpaper, carpets, ceramic glazes, biocides, paints to improve fireproof performance.
