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.

It is not soluble in water. Several variants of zinc borate exist with different zinc/boron ratios and water content. Zinc borate has very low toxicity and is not considered dangerous. The flame retardant properties of zinc borate form the basis of many of its industrial applications.

Paint, pigments, and adhesives

Zinc borate is used in polyvinyl chloride, polyolefins, polyamides, epoxy resins, polyesters, thermoplastic elastomers, rubbers, etc. It is also used in some intumescent systems.

Zinc borate has a synergistic effect with zinc phosphate or barium borate as a corrosion inhibitor pigment.

Resin

In halogen-containing systems, zinc borate is used together with antimony trioxide and alumina trihydrate. It catalyzes the formation of char and creates a protective layer of glass. Zinc catalyzes the release of halogens by forming zinc halides and zinc oxyhalides.

In halogen-free system, zinc borate can be used together with alumina trihydrate, magnesium hydroxide, red phosphorus, or ammonium polyphosphate. During burning the plastics, porous borate ceramics is formed that protect the underlying layers. In presence of silica, borosilicate glass can be formed at plastic burning temperatures.

Other application

Zinc borate is primarily used as a flame retardant in plastics and cellulose fibers, paper, rubbers, and textiles. It is also used in paints, adhesives, and pigments. As a flame retardant, it can replace antimony(III) oxide as a synergist in both halogen-based and halogen-free systems. It is an anti-dripping and char-promoting agent and suppresses the afterglow. In electrical insulator plastics, it suppresses arcing and tracking.

Zinc borate acts as a broad-spectrum fungicide in plastics and wood products
