Abstract
The paper presents the results of a study of the effect of the composition of PVC compound on the heat resistance of fire-retardant materials based on it. The study was carried out on the example of PVC suspension grades of different molecular weight and with different content of the plasticizer. As a result, it was shown that the heat resistance of fire-retardant materials filled with oxidized graphite is significantly affected by both the content of the plasticizer and the molecular weight of PVC. There is also a dependence of the change in the heat resistance of fire-retardant materials on the viscosity of the polymer matrix.
