Our polymerization expertise and advanced plants allow us to achieve truly exceptional thicknesses and shapes. Blocks made from monomer alone up to 400 mm thick, blocks modified with functional copolymers, coloured blocks, mould castings, materials for the hyperbaric market, valves and flanges for very high pressures, domes, polished holes of remarkable depth, and complex objects obtained by moulding and re-machining: we have supplied methacrylates for viewing and radiation protection in nuclear fuel-rod storage pools, phantoms for the calibration of radiomedical machines, materials for maxillofacial surgery, the only polymer certified since 2011 for mucosal implantation, contact lenses for keratoconus correction and, with pride, a window capable of withstanding the depth of the Mariana Trench on an underwater research robot and, looking higher, a pair of secondary windows on the Galileo module orbiting Earth.
