Why Use PEEK? Wet Benches PEEK is a highly chemical resistant plastic so it is often used in semiconductor manufacturing equipment. The semiconductor manufacturing process involves six steps: deposition, photoresist, lithography, etch, ionization and packaging.  Screws, spacers, washers, bearings, rollers and custom parts made from PEEK are often used in the assembly of wet benches. These machines are used in the photoresist process in which silicon wafers are etched to

At Craftech, we make plastic bearings in a wide variety of materials, some of which perform better than others. For a high performance plastic bearings, three of the best materials to use are Vespel®, Torlon® . and PEEK. Let’s take a closer look at these to see what makes them ideal bearing materials.  Vespel® Vespel® by DuPont is the name of a range of high performance polyimide-based plastics. This material is one of

Structure of Semi-Crystalline Polymers Semi-crystalline polymers consist of both crystalline regions and amorphous regions. They have areas that form well-ordered polymer chains, as shown below, along with regions where the polymer chains are randomly ordered. Lamellae refer to the orderly structured crystalline regions. While the loose polymer chains, often called tie molecules, make-up the amorphous regions. This assembly is called a spherulite. There are billions of them in only a few
