2.Application
Zinc borate is of inorganic additive flame retardant, with the features of good hot stability, being resistant to firing and eliminating smoke. In some products, it can replace antimony trioxide, and can be mixed with other inorganic flame retardants with better effect. It is widely applied at the sectors of rubber, plastic, cable, timber, military products, coating, tarpaulin, etc.
 


3.Package, transportation and storage
Package: outer woven bag with inner plastic lining, 25kgs/bag, or as customer's requirements.
Transportation: the product is of dangerous one, which should be protected from damp, rainfall and package damage in 
transportation.
Storage: at dry warehouse with good ventilation.

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 . ZB200 grade's particle size is the smallest, it is recommended to wire and cable applications that need much fine particle size fields.
