The rising voltages in electric vehicles are creating higher requirements on insulation materials. This is why PEEK is increasingly used for this purpose. A problem with this high-performance polymer used to be its adhesion to the secondary insulation material. An epoxy resin now promises to solve the issue.

Due to higher voltages, manufacturers are increasingly using PEEK as insulation material for electric motors.

PEEK and Epoxy Provide Efficient Insulation for High Voltage E-Motor

The conditions in electric vehicles place high demands on the materials used. Therefore, automakers and suppliers must resort to expensive, high-performance plastics. For many applications, cost-effective alternatives are plastics whose properties have been greatly improved by means of treatment with high-energy electron beams.

Over the four trade-show days in November, Formnext 2021 transformed the metropolis of Frankfurt am Main, Germany, into an international innovation center of global additive manufacturing and modern industrial production. At the plastics side, some of the focuses were on the manufacture of voluminous parts, the use of injection molding pellets as a material basis, and the processing of high-performance plastics.

Colored plastics are not just a marketing gimmick, but fulfill important functions with technical components. In particular, they warn of hazards and permit the fast and direct identification of components. However, when coloring such plastic components, the processors are faced with several difficulties. For example, the colorants used must exhibit long-term resistance to high temperatures and must not impair the polymer’s mechanical properties. Therefore, when selecting the colorant, compounders and processors must observe several important points.

Ultra high performance polymers such as polyaryletherketones (PAEK) are typically not thermoformable for thick gauge applications because of their semi-crystalline nature.

PEEK was invented a little over 40 years ago, and so is a relatively young high-performing thermoplastic polymer. Nevertheless, continuous development of products and processing technologies enables a range of advanced applications in the automotive, aerospace, electronics, energy, and food-and-beverage sectors, as well as the medical industry.
