At the end of 2017, Evonik put the world´s most advanced stretching and polishing plant for aviation materials made of ACRYLITEÂ® into operation, the company said.
In Weiterstadt, 20 kilometers South of Frankfurt, the company is now producing polymethyl methacrylate (PMMA) sheets 5.4 meters long and 3.7 meters wide — the largest format available worldwide.
Before production begins, an extensive validation phase must first be completed by an external company. Due to the stringent standards in the aviation industry, the products must first obtain an aviation certification. For this purpose, Evonik will take the first PMMA sheets from the new plant in order to certify the material in accordance with Mil P-25690 for the North American market and EN 4366 for the European market. The first of the necessary tests have already successfully passed.
At the same time, the first partners in the aviation industry are already receiving samples. This enables them to verify for themselves the advantages of the large-format PMMA sheets. These include — in addition to the increased design options – highly efficient production processes and reduced offcut quantities.
