Elastomeric polymer distilled bitumen waterproofing membrane.FLEXO S6 P is a prefabricated ELASTOMERIC waterproofing membrane offering excellent performance. Made from a special modified distilled bitumen compound with a high percentage of elastomeric SBS thermoplastic rubbers (Styrene-Butadiene-Styrene). FLEXO S6 P 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. FLEXO S6 P has a polyester nonwoven carrier stabilized with glass strands parallel to the machine direction. The carrier gives tensile strength in all directions, as well as good puncture resistance and dimensional stability.
