WebThe TGA thermograms of the individual plastic polymers showed that polystyrene showed the main degradation peak at a lower temperature (~420 °C) than the other polymers and polyethylene had the highest degradation temperature (~480 °C). The order of thermal degradation was PS WebThe change of PP thermal degradation pathway by the synergistic and catalytic effects of PP- g -MA and Co NPs in the PP matrix was found to be responsible for the decreased combustion rates of PP. Strong interactions between PP and Co NPs formed by the PP- g -MA was further confirmed by attenuated total reflection-Fourier transform infrared spec...

Web1 Nov 2024 · Because polypropylene contains both methyl and methylene groups, it has four peaks between 3000 and 2850, as seen in Figure 1, whereas, since polyethylene only contains CH2, it has two peaks in this region (1,2). So, a quick way to distinguish between these two polymers would be to simply count the number of peaks between 2850 and 3000. WebThermo gravimetric analysis (TGA) TGA of the pure UHMWPE, PP, and UHMWPE/PP blends was performed to evaluate the impact of PP content on the thermal stability of UHMWPE. TGA curves in Figure-2 shows the degradation temperature of pure po lymers and their blends. It can be observed that all TGA curves are single- ...
