| Uses: |
1. Zinc Borate is one multi-functional synergistic flame retardant with Antimony Oxide etc. additives in polymers to improve flame retardant performance
2. it 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.
3. It 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. |
