The Trelleborg MainLiner is the best choice when you need a customized solution for longer straight CIPP lining with bends up to 30°.
The MainLiner is coated with an elastic polypropylene-coating, which varies from flexible to robust, in correlation to the tube diameter. This gives the liner optimal processing properties adapted to the respective area of application.
Thanks to this elasticity, inversions of smaller diameters are easy to carry out, even during cold temperatures.
The Trelleborg MainLiner has outstanding impregnation properties. It is recommended to be used in combination with Trelleborg epoxy resin systems, but is suitable for unsaturated polyester resin (UP), polyurethane (PU) and vinyl ester resins as well.
3 - 32 mm [0.12" - 1.26"], single- or multi layer composition, depending on wall thickness
Epoxy resins, unsaturated Polyester resin (UP), Polyurethane (PU) and Vinyl ester resin (VE) are suitable for the Trelleborg MainLiner
