Innovative extrusion process for coloured ETFE architectural membranes wins 2nd prize in DuPont Plunkett Awards 2013
Neu-Isenburg, Germany, November 2013. Trifluor Kunststoff GmbH, Ochtrup, has taken second place in the DuPont Plunkett Awards 2013 in the EMEA Region (Europe, Middle East and Africa). The company received the prize for an innovative extrusion process for the production of coloured and structured architectural membranes of ethylene tetrafluoroethylene (ETFE). The jury was particularly impressed by the fact that, due to an in-house recycling technology for fluoroplastics, these membranes can also be made from 100 % recycled material and therefore can contribute to greater sustainability.
The Plunkett Awards 2013 coincide with the 75th anniversary of the discovery of PTFE by DuPont scientist Dr. Roy Plunkett and reward outstanding technical developments in the field of fluoroplastics. Erik Winkler, Account Manager Fluoropolymer Solutions, DuPont Chemicals & Fluoroproducts (DC&F) EMEA, presented the sculpture and the prize money of 5,000 USD to the Managing Director of Trifluor, Hermann Jenewein.
Before now, it was only possible to create shadowing and colour effects on transparent ETFE architectural membranes by printing. Jenewein explains: “Printed shadowing effects or colourations have the disadvantage that they normally have poor UV resistance and fade over the course of time. With our process, the colour pigments are added directly during film extrusion. As a result, they are bound firmly into the polymer matrix of the 0.2 mm thick ETFE membranes, ensuring that the colouration or shadowing effect has long-term UV stability.”
Through variable pigment concentrations, Tiffany effects and different shadowing intensities can be created, resulting in new aesthetic design possibilities for roof and façade constructions, e.g. for public buildings. A prototype façade, which Trifluor has installed at its head office in Ochtrup, consists of a coloured membrane provided with Tiffany effects. The membrane is made of Tefzel® ETFE from DuPont, and is backlit at night with the help of LEDs.
