 have been systematically studied in this paper. Firstly, effects of single groups on PVC flame retardant properties were studied, including aluminum hydroxide (ATH), antimony trioxide (Sb2O3). Study found that antimony trioxide is the better flame retardant for PVC. Adding 4phr Sb2O3 into PVC，the LOI can reach 29.4%. Then we studied effects of binary system, aluminum hydroxide - antimony trioxide(Sb2O3-ATH) and zinc - aluminum hydroxide(ZB-ATH), on PVC flame retardant properties. The LOI can be as high as 30.3 when the amount of ATH is 20phr and Sb2O3 is 3phr, while the LOI increased by 5% by adding 3 phr ZB and 20phr Al(OH)3 into PVC, the SDR can decrease to 66.98. Study found that both zinc borate and antimony trioxide have synergistic effects on aluminum hydroxide.&picture=http://www.aascit.org/aascit/decorators/img/journal/916.jpg)

Effects of the inorganic flame retardants on the oxygen index of flexible Polyvinyl chloride (PVC) have been systematically studied in this paper. Firstly, effects of single groups on PVC flame retardant properties were studied, including aluminum hydroxide (ATH), antimony trioxide (Sb2O3). Study found that antimony trioxide is the better flame retardant for PVC. Adding 4phr Sb2O3 into PVC，the LOI can reach 29.4%. Then we studied effects of binary system, aluminum hydroxide - antimony trioxide(Sb2O3-ATH) and zinc - aluminum hydroxide(ZB-ATH), on PVC flame retardant properties.

Study found that both zinc borate and antimony trioxide have synergistic effects on aluminum hydroxide.
