POLYBOND and POLYBOND MINERAL are prefabricated waterproof plastomeric membranes capable of offering excellent performance. They are made from a POLYPROPYLENE-modified distilled bitumen compound and a heavyweight polyester staple-fibre nonwoven carrier, reinforced and stabilized with glass strands parallel to the machine direction. The general characteristics guarantee excellent mechanical properties, excellent ultimate elongation, high puncture resistance and dimensional stability. The special compound gives remarkable low temperature flexibility properties. The sophisticated manufacturing technology assures product quality, stability and lengthy service life. The POLYBOND and POLYBOND MINERAL membranes are produced to the quality standards set by NAT^® technology the innovative manufacturing system for the control of polymer matrix ageing in bituminous membranes.
