Gehr Kunststoffwerk in Mannheim, Germany (U.S. offices in Boothwyn, Pa.) is working on extrusion of a lignin-based thermoplastic made from a byproduct of paper production. Called Arboform, the resin is made by Tecnaro GmbH in Eisenach, Germany. Tecnaro's Arboform polymers were initially thermosets, but in 2004, Tecnaro developed thermoplastic Arboform, which processes at very low temperatures (176 to 284 F). Tecnaro is compounding thermoplastic Arboform with oils, waxes, and natural fibers like flax and hemp to make a material that processes on a conventional single-screw extruder. Gehr's target market is pen tubes. Gehr: +49 (631) 87890/www.gehr.de . Tecnaro: +49 (3691) 62 13 20/www.tecnaro.de
