Abstract
The effects of accelerated heat-aging on three PVC roofing membranes was determined using thermogravimetry (TG), dynamic mechanical thermal analysis (DMA) and tensile testing. The heat-aging was done at 100C and 130C. In general, it was found that the degradation of the reinforced PVC roofing membranes was proportional to the aging temperature and exposure time. Furthermore, it was found that these thermoanalytical techniques can be used to not only record the changes incurred by the samples due to heat-aging but also, provide a ranking of the heat stability of the various materials.
