Polypropylene (S)


Layfield's supported styles of Polypropylene [PP (S)] combine the unique attributes of the PP polymer formulation with the mechanical strength of a 250 lb polyester scrim. PP (S) is composed of the same industry proven blend of polymers and additives that is found in Layfield's unsupported styles of PP.

PP (S) brings together two soft, supple PP films laminated onto a reinforcing 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)  carries the NSF 61 certification for contact with potable water. This resilient polymer is also inert to surfactants which can cause environmental stress cracking in HDPE.

PP(S) offers a combination of strength, flexibility, and UV resistance that makes it a clear choice for floating cover applications. PP (S) maintains it's flexibility at low temperatures, making severe winter installations or service conditions an easy application to resolve. In any water or waste water containment project PP (S) is a clear choice when a strong and chemically resistant geomembrane is required.
