EPD: Ketone ethylene (KEE HP) polyester reinforced single-ply roofing membranes, 50 mil, 1.27 mm, 1.6 kg/m2, Sure-Flex TM KEE HP (Carlisle SynTec Systems, Greenville plant)

Carlisle’s Sure-Flex TM KEE HP membrane is manufactured using DuPont® Elvaloy® KEE HP resin modifier. KEE HP enhances the performance of PVC compounds by providing outstanding thermal stability and flexibility while extending the low- and high-temperature performance limits of standard KEE. The addition of Elvaloy KEE HP, a non-volatile resin modifier, provides enhanced heat and chemical resistance. The physical properties of the membrane are enhanced by a polyester fabric that is encapsulated by thick KEE HP-based top and bottom plies. The smooth surface of the KEE HP membrane allows a total surface fusion weld over a wide temperature range, creating a consistent, watertight, one-piece roof assembly.
