Applications:


Zinc Borate is one multi-functional synergistic flame retardant with Antimony Oxide etc additives in polymers to improve flame retardant performance, it can reduce smoke evolution and adjust the balance of flame retardant properties versus mechanical, electrical and other properties.
Zinc Borate is widely used in PVC applications such as carpet, conveyor belt, wire and cable, and in Nylon, PE, PP etc engineering plastics of halogen free flame retardant systems based on Al(OH)3 and Mg(OH)3, intumescent coating and painting, ceramic glaze, milk glass, decorative paper etc fields.
Zinc Borate is also used in wood composite as fungicide to prevent from decay fungi and subterranean termites .
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 synergistic effect with zinc phosphate or barium borate as a corrosion inhibitor pigment.
Zinc borate acts as a broad-spectrum fungicide in plastics and wood products.
Zinc borate can be used as a flux in some ceramics. In electrical insulators it improves the ceramics properties.
Nanopowder zinc borate can be used for the applications above, and also for improving the frictional properties of lubricating oils.
