PRODUCT PAA-SF-Liner™ – Epoxy The PAA-SF-Liner™ impregnated with epoxy resin is a high quality liner designed for renewal of DN100-DN1000 gravity pipelines, laterals and pipes in sensitive areas. The PAA-SF-Liner TM consists of up to 90% regenerated fibers and is a multi-layered polyester needle felt, coated with high temperature resistant polypropylene (PP). The PAA-SF-Liner™ with epoxy is available in diameters ranging from DN100 mm to DN1000 mm with wall thickness ranging from 3 to 15 mm. The PAA-SF-Liner™ is tailored to each individual installation at our ISO certified factory. The liner can be designed to fit into pipe sections with dimension changes. The PAA-SF-Liner™ can be inverted into the existing pipe by means of water or air pressure. PERFORMANCE The PAA-SF-Liner™ has been used by the Aarsleff Group for renewal of gravity pipelines for more than 25 years.
