Polyetheretherketone ranks among the high Performance thermoplastics thanks to its high melting point of 649 °F (343 °C) and its maximum continuous operating temperature of 500 °F (260 °C). Its particular chemical structure makes PEEK largely stable against thermal and chemical damage and permits its usage inside the body. In case of fire, the smoke development of PEEK is the lowest of all thermoplastics; the material is therefore used in aviation. FIL-A-GEHR PEEKTM is an experimental filament with a processing temperature of 707 °F (375 °C) in the heated chamber 202 °F (180 °C). The material is specifically apt for use on 3D printers.
