Zinc borate

Chemical Name: Zinc borate
Brand Name: Ecoflame I-223
CAS NO.: 1332-07-6
Chemical Structure: 2ZnO· 2B2O3·3H2O

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 inNylon,
PE, PP etc engineering plastics of halogen free flame retardant systems based on Al(OH)3 and Mg(OH)3, in
tumescent coating and painting, ceramic glaze, milk glass, decorative paper etc fields.
