Arkema Inc. (King of Prussia, Pa.) highlighted at COMPOSITES 2013 several innovative chemical technologies, including Nanostrength, a new family of self-assembling block copolymers that enhance epoxy resin system performance. Also on display was a new technology for manufacturing Arkema’s Kynar PVDF fluoropolymer foam product at very low density. The process encapsulates a highly foamed center layer with solid interior and exterior layers. The technology reportedly allows production of very lightweight, low smoke and flame multilayer piping. Applications for the piping include not only oil and gas plants and other chemical processing operations, but also aircraft and automobiles, where ductwork is a target for lightweighting efforts.
