RUFCO® 2000B, 3000B and 4000B are membranes consisting of a very flexible, linear low-density polyethylene (LLDPE). LLDPE provides high elongation, tremendous tear resistance and bursting strength. A minimum carbon black content of 2.0% provides excellent protection from UV rays and harsh weather conditions. Manufactured from virgin resins, RUFCO® 2000B, 3000B and 4000B do not contain plasticizers which can migrate to the surface, causing premature aging.
RUFCO® 2000B, 3000B and 4000B are used in applications that require excellent outdoor longevity and chemical resistance. These are very flexible materials that will conform to uneven surfaces. Rufco® 2000B, 3000B and 4000B meet the GRI-GM17 Standard Specification.
