Applications:
- Zinc borate is primarily used as a flame retardant in plastics and cellulose fibers, paper, rubbers and textiles. It is also used in paints, adhesieves, and pigments. As a flame retardant, it can replace antimony(lll) oxide as a synergist in both halogen-based and halogen-free systems.(2)It is an anti-dripping and char-promoting agent, and suppresses the afterglow. In electrical insulator plastics it suppresses arcing and tracking.
- In halogen-containing systems, zinc borate is used together with antimony trioxide and alumina trihydrate. It catalyzes formation of char and creates a protective layer of glass. Zinc catalyzes the release of halogens by forming zinc halides and zinc oxyhalides.
- Zinc borate is used in polyvinyl chloride, polyolifins,polyamides,epoxy.resins,polysters, thermoplastic elastomers,rubbers, etc. It is also used in some instumescnts systems.
- Zinc borate can be used as a flux in some ceramics in electrical insulators it improves ceramic properties.
- Nanopowder zinc borate can be used for the application above, and also for improving the frictional properties of lubricating oils.
Dosage
Zinc borate has snyergistic effect with zinc phosphate and barium borate as corrosion inhibitor pigment. Zinc borate act as a broad-spectrum fungiside in plastic and wood products.
