Description
Zinc borate is an inorganic compound, a borate of zinc. It is white crystalline or amorphus powder insoluble in water. Its toxicity is low.
Application
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.
