Web14 Apr 2024 · The purpose of this study was to investigate the thermal stability and the decomposition kinetics of ethylene–propylene–diene monomer (EPDM) composite samples loaded with and without lead powder (50, 100, and 200 phr lead) using thermogravimetric analysis (TGA). TGA was carried out at different heating rates (5, 10, 20, and 30 °C/min) … WebTGA measurements can be used to compare different types of carbon black. From the thermal degradation behavior, it is possible to check the specification of a carbon black sample with regard to its surface area. 1/2 70 80 90 100 110 120 665 670 675 680 685 690 695 T 1/ 2 in °C DBP value in ml/100g Conclusions
