PEEK Fasteners and Custom Parts

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. …

Nylon Fasteners: Hex Nuts, Hex Head Cap Screws, Flat Washers, Spacers, and Standoffs

Nylon  Fasteners

Nylon is used to make plastic fasteners such as nylon screws, hex nuts, hex head cap screws, flat washers and cable ties. This material is also used for printed circuit board hardware, automotive parts and fabrics. In this blog we will discuss nylon 6/6 fasteners.

Development of Nylon 
Nylon was first developed in the late 1930’s by Wallace Carothers at DuPont.

Semitron® MPR100 Sheet and Bar

Semitron® MPR1000 for the Semiconductor Industry

Semitron® MPR1000 is a new engineering material developed by Mitsuibishi Chemical Advanced Materials for semiconductor applications. MPR stands for maximum plasma resistance. It is intended for use in vacuum plasma chambers to replace ceramics and quartz for ICU production.  Ceramics are more expensive and quartz is prone to break. It also performs better in this application than PEEK, PAI such as Torlon® or polyimide thermoplastics.  For example MRP1000 has an increased life in plasma chambers of up to 25X in ozone than polyimides such as Vespel®.…
