TPO MEMBRANE SYSTEMS (11/97F)

Sure-Weld Thermoplastic Polyolefin (TPO) roof membranes are not adversely affected by most common materials and chemicals encountered in a roof environment. Since the field seam is heat welded, it is as resistant to chemicals as the base sheet. The best course of action to take if unusual substances will contact the membrane, is to evaluate their effect on the membrane in the laboratory. Carlisle SynTec's Laboratory is equipped to perform this testing, interpret the results, and provide a recommendation.
