The continuous operating temperature of this high-performance plastic ranges between approximately -40° C and +260° C. It features an extraordinary combination of very high rigidity, hardness, tensile strength and bending strength (high toughness and fatigue strength), high heat deflection temperature and excellent resistance to disinfectants and detergents. The hydrolytic stability is exceptionally high, so that repeated sterilization in steam is possible without any problems. PEEK is self-extinguishing according to UL94 specifications. The raw materials used meet the requirements of FDA and EU 10/2011 for food contact materials.
The processing temperature for the filament is 375°C in the heated chamber (180°C). The material is specifically designed for use on 3D printers.
