Abstract
The effect of heat-aging at 100 °C and 130°C on three EPDM roofing materials was studied by thermogravimetry (TGA), dynamic mechanical thermal analysis (DMA) and tensile testing. It was found that both TGA and DMA can be used in a routine manner to explain the changes in mechanical properties of EPDM roofing membranes. In general, the results showed that the degradation of the material increased with heating temperature and exposure duration. It was also shown that aging at elevated temperatures can reduce the time required to evaluate the effect of heat on mechanical properties of polymer-based roofing materials.
