Arkema has developed a Kynar ADX resin technology available for bonding Kynar polyvinylidene fluoride (PVDF) to polyolefin resins in potable water piping.
Kynar PVDF can be extruded and bonded with Kynar ADX as a barrier layer to a polyolefin multilayer pipe system that is reliable and long lasting. This multilayer piping combines the benefits of polyolefin (high flexibility, therefore supplied in coils for easy installation) with those of PVDF resin: high chemical resistance, high purity, low biofilm formation, long service life and very low permeation (for safe transportation of water through contaminated land).
This product can withstand disinfectants such as chlorine, chlorine dioxide, chloramines, sodium hypochlorite, hypochlorous acid, and other aggressive chemicals added to drinking water. 150km of this multilayer piping have already been installed by water companies in France to the full satisfaction of end-users and municipalities, according to Arkema.
