Elastomeric-plastomeric polymer distilled bitumen waterproofing membrane. POLYBOND P is a prefabricated ELASTOMERIC-PLASTOMERIC (Plastomer-Polymer Bitumen) waterproofing membrane capable of 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 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. POLYBOND P has a spunbond polyester nonwoven carrier stabilized with glass strands parallel to the machine direction. The carrier gives good tensile strength (in all directions) and puncture resistance, with excellent dimensional stability.
