Our research aimed to find efficient heavy metal free flame retardant for cable grade plasticized poly(vinyl chloride) comparable to the conventional flame retardants. One of the candidates, is artificial silicate (Oxydtron®) proved to be an efficient flame retardant and surprisingly showed excellent heat stabilizing effect as well. Tests were done on limiting oxygen index (L.O.I.), heat stability by static method and Congo-red, differential scanning calorimetry (DSC). These thermal tests proved the ability of Oxydtron to improve the properties of poly(vinyl chloride) at high temperatures reducing the risks associated with combustion of plasticized poly(vinyl chloride) by increasing its thermal stability, which will lead to open a new horizon in the poly(vinyl chloride) industry. Unfortunately, this excellent material is not available yet in white color because of its coloring impurities.
