Mule-Hide Products

 New Mule-Hide PVC KEE HP roofing systems feature improved thermal performance, chemical resistance, cold-temperature flexibility, weldability and aesthetics. The membranes and accessories are manufactured with DuPont Elvaloy® ketone ethylene ester (KEE) HP polymer, a solid, high-performance, high-molecular-weight resin modifier. The polymer requires less plasticizing material to make the membrane permanently flexible and reduces plasticizer migration from the membrane, resulting in more contractor-friendly installations and helping preserve the membrane’s physical attributes for long-term performance. Membranes are available in 50-, 60- and 80-mil thicknesses. Each thickness is available in 5- and 10-foot-wide rolls that can be used in mechanically fastened or fully adhered installations. Membranes are currently available in white. Cool Tan and Cool Gray will be added later this year, as will Mule-Hide PVC KEE HP Fleece Back membrane in white. For more information, visit
