PEEK Parts: Description and Uses

PEEK Parts: Description and Uses
PEEK, also known as polyetheretherketone, is a high performance, engineering plastic. It is a semi-crystalline, high temperature resistant thermoplastic. It is one of the most popular materials we manufacture parts from here at Craftech®. PEEK has a strong following in the aerospace and semiconductor industries. In this article, we will describe some of the excellent properties that make this plastic material so popular.

Mechanical Properties
The processing conditions used to mold PEEK can influence its crystallinity and mechanical properties.

Teflon® (PTFE) Fasteners: Screws, Hex Huts, Hex Head Cap Screws and Custom Parts

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. …

Top Four Grades of PEEK

The four top grades of PEEK are: unfilled, 30% glass-filled, 30% carbon-filled, and 20% PTFE and graphite filled. These materials are manufactered into fasteners and components such as bearings, screws, flat washers, hex nuts, gears, and medical components in addition to many custom shapes. The properties of each and the industries they are used in are discussed below.
Unfilled-PEEK
Of the top four grades of PEEK, unfilled-PEEK  (polyetheretherketone) is the most common grade.  It is a semi-crystalline polymer. …
