To produce flame resistance rubber from natural rubber like polychloroprene rubber does, one can make by adding 10 phr. antimony trioxide (Sb2O3) and 26 phr magnesium chloride in the ebonite rubber compound which has carbon black as a filler. The ratio of antimony to chloride used is 1 to 3 gives the best results equivalent to polychloroprene rubber does. Thermal gravimetric analysis (TGA) also shows the higher temperature for losing weight when using these chemicals.
