Flex Membrane

Flex membranes coated with DuPont's Elvaloy KEE (ketone ethylene ester) provide state-of-the-art performance for thermoplastic single-ply roofing systems. Flex PVC flexible single-ply roofing membranes are made using special UV inhibitors to provide a proven long-term roofing solution. The Flex TPO thermoplastic single-ply system with advanced polymerization technology combines durability and weatherproof properties.

Established in 1990, Flex Roofing Systems (Flex Membrane International Corp.) pioneered the manufacturing of modified PVC single ply roofing membranes incorporating DuPont Elvaloy KEE, a unique plasticizer that keeps the material indefinitely flexible, while making it highly resistant to environmental and temperature extremes and exposure to a wide range of chemicals and pollutants.
