Polymer-based materials handle higher temperatures

Paul Boughton
Quadrant is expanding design and performance possibilities for machined parts in high-temperature applications with the launch of Duratron D7000 PI polyimides and modified Peek Semitron MP370. The new materials are said to be a cost-effective option for machine designers and engineers who currently have to use alternative materials.
Duratron D7000 PI and new bearing-grade Duratron D7015G PI are high-performance polyimide materials that bring the benefits of polymer materials to applications operating in the region of 315 degrees C. While polyimide has been widely used in semiconductor and electronics manufacturing equipment for years, Quadrant's new Duratron D7000 PI materials are available in a wider range of sheet sizes and tube configurations than other PIs. As a result, new opportunities in parts design are made possible.
This launch represents an important addition to Quadrant's portfolio of ultra-high-temperature, polyimide materials. Quadrant recently rebranded its existing portfolio of PAI, PBI and PEI high-performance advanced engineering plastics (AEPs) under the brand Duratron in order to simplify choice and make products easier to identify, based on their performance attributes. The new Duratron PI grades, available in a range of sizes, will help engineers to more precisely and economically select the optimum materials for specific applications and environments.
New, homogenous, ceramic-filled Peek Semitron MP370 gives semiconductor test socket designers a stable platform for innovative design ideas by enabling builders to more closely tailor the socket material to the application environment. An extension to the Duratron PAI (Torlon), Ketron Peek and Semitron ESD materials, Semitron MP370 Peek is not subject to the 'soft centre' or inconsistent physical properties that can be found in injection moulded shapes. As a result of its excellent machinability, engineers can generate very small holes and very tight hole patterns for the first time with a generic, ceramic-filled Peek.
Dr Stephan Glander, global director of research and market development at Quadrant, comments: "Quadrant's approach of helping to select the 'right' material for each application brings real value to equipment builders by not immediately jumping to ultra-exotic (and ultra-high priced) solutions. We are excited to fill current performance gaps with these innovative material advances for a broad range of industrial sectors."
