Description
PEEK ( Ketone ) Rod :
PEEK Rod is a semi crystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. The processing conditions used to mold PEEK can influence the crystallinity, and hence the mechanical properties
PEEK Rod mechanical properties at elevated temperatures have led to it being used in at least two varieties of Rep rap extruded as thermal insulation. This means the main mechanical structure of the extruded can be made of the same material that is being extruded, provided that the PEEK insulator prevents heat from traveling beyond the intended melt zone. A disadvantage is the high price, which limits its application to high value items.
