Low-melting glass has been synthesized in the system PbO-ZnO-B2O3 and Na2O-P2O5-MoO3 and its composition has been developed. The effect of the glass chemical composition on the softening temperature and the change of appearance during the heating have been established. Polypropylene-based composite with different content of glass powder as a filler was obtained. Thermo-physical properties of the composites were determined. Introduction of glass powder to the polypropylene composition damaged the material structure homogeneity. Using DTA method it was established that the developed filler shifts the temperature of polymer complete combustion toward higher temperature by above 40 K.
