PEEK or polyetheretherketone is a high performance, engineered plastic. It is one of the materials of choice for spinal implants as well as trauma fixation. Trauma fixation is the repair of broken bones or any bodily injury that can result from force or violence applied to the human body. It is also used for cardiovascular implants as well as in orthopedic surgery and dentistry. While in the past, metals such as titanium have often been used for these purposes,…
Ultem® PEI (polyetherimide)
Ultem® PEI is a semi-transparent high temperature plastic. It is used to make custom parts as well as fasteners such as screws, hex nuts, washers, threaded studs and spacers. It can be both molded and machined. Ultem® hardware is also available in glass-filled grades for enhanced strength and stiffness. (Glass-filled grades are opaque.) Ultem® 1000 is the natural grade and Ultem® 2300 is the glass-filled grade.
Ultem® PEI Properties:
It is an amorphous plastic.…
Teflon® (PTFE) Fasteners
Teflon® (PTFE) is fabricated into fasteners. These include screws, hex nuts, hex head cap screws, flat washers etc. It is also used to fabricate custom parts. However, this material can only be turned, or made into parts on a CNC machine. It can also be compression molded. But it cannot be injection molded. It is not a thermoplastic.
These fasteners and custom parts are used in applications where high heat and chemical resistance are required. …
