An inside look at our engineering expertise
Introduction to High-Performance Polyimides
In modern engineering, deploying the latest high-performance polymers, particularly polyimide materials like Ducoya®, is pivotal in advancing technological applications. These materials are renowned for their exceptional thermal capability, dimensional stability with minimal thermal expansion, interesting electrical properties and outstanding mechanical properties, which make polyimides indispensable in high-stress, harsh, high-temperature environments.
We cover the wide range of polyimide plastics available in a separate article. Polyimides can have a wide range of properties, and it is essential to choose carefully. Here, we will discuss the most recently introduced polyimide, Ducoya G series by Duvelco.
Interesting Properties of Polyimide Materials
Aromatic polyimides, a family of high-performance polyimide plastics, are celebrated for maintaining integrity and performance in extreme conditions. One single property of a chosen polyimide is not determinant; the combination of multiple interesting properties in a single plastic material makes polyimide so attractive. This section explores the unique combinations of characteristics that make polyimides the material of choice for some of the most critical engineering applications.
We will cover some of these properties below, but for a complete list of the interesting properties of Ducoya G series high-performance polyimides, please request the document ‘Interesting properties of Ducoya’ on the Duvelco website www.duvelco.com.
Thermal Stability
Ducoya polyimide materials can withstand temperatures ranging from cryogenic levels up to 400°C continuous operation in a favourable chemical environment. Excursions to higher temperatures exceeding 600°C are permitted, with the length of the excursion determining the maximum temperature. This exceptional thermal latitude ensures that components made from Ducoya do not deform or degrade in harsh thermal environments.
What can be even more interesting is that the Ducoya G series does not exhibit a glass transition, also abbreviated to Tg, or other troublesome, property-changing transitions over this extensive temperature range, significantly simplifying the design of components and consideration of ‘off-design’ operation.
Mechanical Strength
Despite their lightweight nature, polyimides exhibit superior mechanical strength. They can withstand significant mechanical stress, making them ideal for aerospace, automotive, and industrial components.
Chemical Resistance
Polyimides are highly resistant to a wide range of chemicals, including lubricants, fuels, and coolants. This resistance is crucial for applications in harsh chemical environments and scenarios where material exposure to aggressive substances is frequent.
Electrical Insulation
With excellent dielectric properties, polyimides serve as effective insulators in electronic and electrical systems. This characteristic is essential for ensuring the reliability and safety of electrical components, particularly in the semiconductor and aerospace industries.
