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®. … Read more
PEEK custom parts and PEEK fasteners such as screws, hex heads, hex nuts, set screws, flat washers and threaded studs are used in a wide range of industries.These include semiconductor manufacturing equipment, oil and gas, telecommunications, medical equipment and medical parts for implantation in the human body. It is also used widely in the semiconductor equipment manufacturing industry, and the electronics and food processing industries. PEEK stands for polyetheretherketone.
Properties of Polyetheretherketone

94 V-0 flammability rating
Excellent hydrolysis resistance. … Read more
TORLON®, Polyamide-imide (PAI)
TORLON® is the Solvay brand name for polyamide-imide or PAI. It can be machined into custom parts, screws and other fasteners including hex nuts. set screws, hex head cap screws and threaded studs. Polyamide-imides demonstrate exceptional mechanical, thermal and chemical resistance properties making them well suited to severe environmental service.
High Heat Performance
Torlon®, polyamide-imide have exceptionally high heat performance with a continuous service temperature of 260°C or 500°F and are inherently flame resistant. … Read more
Plastic vented screws are often used in vacuum systems. They either have a hole drilled through their axis or along the side of the screw. This hole allows the evacuation of trapped pockets of air and surface contaminates from blind-tapped holes. A bind-tapped hole is one that is drilled to a specified depth without breaking through the other side of the work piece.
Vacuum Systems in HV, and UHV
Vented screws allow for faster and more efficient pump-down of High Vacuum (HV), … Read more
DuPont Vespel® Polyimide
Vespel® is the DuPont trade name for a group of materials used to make a wide variety of components including custom parts such as valve seals, thrust washers, pintle tips and actuator guide bushings. Some Vespel® grades are used to make fasteners such as screws, hex cap screws, hex nuts and locking fasteners, etc. It is a high performance plastic used principally in the semiconductor, aerospace and in transportation applications. In this blog we will focus on the use of Vespel® in the aerospace industry. … Read more
