Elastomeric-plastomeric polymer distilled bitumen membrane, REOXTHENE Ultralight Technology. ANTIRADICE LIGHT P is a prefabricated ELASTOMERIC-PLASTOMERIC membrane offering good performance, by virtue of a higher percentage of polymers such as POLYPROPYLENE (APP) and POLYOLEFIN (APAO). Its special formulation, comprising the exclusive REOXTHENE Ultralight Technology compound, also results in the only weight-to-thickness ratios of their kind. The addition of special anti-ageing additives provides blends with superior, long-lasting performance characteristics. ANTIRADICE LIGHT P is a membrane designed to deliver unbeatable resistance to root penetration according to standard EN 13948. The special compound enhanced with the addition of PREVENTOL B5 from LANXESS actually makes an excellent chemical barrier against membrane puncture by plant roots, ensuring the membrane delivers perfect watertightness and resistance to aggressive chemicals. ANTIRADICE LIGHT 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.
