This is an injection moulded, glass filled PEEK part, made to our specification to be used for a hybrid material extruder. It is made so that you can insert a Teflon/PFA tube, ideal for Bowden extruder, but also great for any other extruder because you can use a piece of Teflon inserted into this insulator. This allows for better printing with PLA, which tends to require a low friction and slightly flexible material to prevent jamming. This part is compatible with the complete Ultimaker Original and Ultimaker Original+.
This part is also included in the Hot End v2 bundle. It's one of the essential parts for trouble free extrusion. PEEK is a thermoplast that is stable at very high temperatures, common applications include aerospace and other high pressure high-temperature applications. Because this PEEK is part glass filled, it has a higher thermal stability than most machined PEEK parts you can buy. Properties of the PEEK material:
High temperature resistance of 285C
Excellent toughness with high rigidity and fatigue resistance
Self-lubrication, wear resistance, has the best slide performance in all the plastics
Can be used in the requirement of low coefficient of friction
Excellent resistance to hydrolysis
Excellent chemical resistance, similar to nickel steel
Resistance to radiation (the last thing you want during a nuclear war is your extruder failing on you!)
