Characterization of polymer modified bituminous roofing membranes using thermal analysis
Abstract The thermal properties influencing seam performance of polymer modified bituminous roofing membranes are investigated using thermogravimetry and differential scanning calorimetry. Ten different commercial roofing materials are included: three atactic polypropylene (APP) modified bitumens and seven styrene-butadiene-styrene copolymer (SBS) modified bitumens. The results show that the difference in specific heat among different SBS or APP products was small. However, the specific heat of APP products was approximately 0.2 J $ g^{−1} $ $ K^{−1} $ higher than that of SBS products. It may indicate that for APP products a higher amount of energy is required for welding. Overheating of the membranes above 200°C during heat welding may cause decomposition in the polymer modified bitumen, since the degradation of pyrolysable organics begins at ∼200°C.
