Ameriover’s Supported Polypropylene (PP (S) brings together two soft, supple PP films laminated around a reinforcing 250 lb polyester scrim layer. The resulting geomembrane is strong enough to hang vertically in the form of a baffle curtain or tank liner, and durable enough to leave exposed to the elements for many years. PP (S) is UV stabilized with 2 to 3% carbon black included in the formulation. PP (S) provides excellent cold temperature flexibility, long term UV resistance, and substantial tensile strength. PP (S) is chemically resistant to water purification chemicals, and carries the NSF 61 certification for contact with potable water. This resilient polymer is also inert to surfactants that can cause environmental stress cracking in HDPE. PP (S) offers a combination of strength and flexibility that has led to it being a material  of choice for floating covers. PP (S) maintains its flexibility at low temperatures, making severe winter installations or service conditions an easy application to resolve. In any water or wastewater containment project PP (S) is a clear choice when a strong and chemically resistant geomembrane is required. Available in 36, 45, and 60 mil. Applications • Baffle Curtains • Tank Liners • Waste Water Containment • Potable Water Containment • Floating Covers
