“…The flame retardant coating plays an important role in the performance of the flame retardant. Comparing with DOP, ECO, sunflower oil [11], safflower oil [12], glycerol [13], oleic acid [14], rice fatty acid [15], cardanol [16] soybean oil [17,18], epoxidized sunflower oil [19], glycerol triisovalerate [20], because all the above plasticizers burn easily which could not play any role on flame retardancy for PVC blends, but COPE not only plasticizes PVC effectively but also reduces the flammability of PVC blends.…”
