Elastomeric-plastomeric polymer distilled bitumen waterproofing membrane. POLYFLEX EL C is a prefabricated ELASTOMERIC-PLASTOMERIC (Plastomer-Polymer Bitumen) waterproofing membrane offering excellent performance. Made from a special distilled bitumen compound modified with a high percentage of special polymers such as POLYPROPYLENE (APP) and POLYOLEFIN (APAO), with the addition of special anti-ageing additives that provide blends with superior performance characteristics. POLYBOND EL C is a membrane produced to the standards set by NAT technology, the innovative production system for the control of polymer matrix ageing in bitumen membranes. POLYFLEX EL C has a COMPOSITE spunbond polyester nonwoven carrier, stabilized with glass strands in both directions. The carrier gives great tensile strength and excellent dimensional stability, in both the cross and machine direction (isotropic behaviour).
