With the continuous popularization and development of new energy vehicles, IGBT module, one of the core components in the three-electric system of electric vehicles, has higher and higher requirements for materials. Based on the needs of IGBT, PPS, which has incomparable performance and cost-effective advantages of other thermoplastic engineering plastics, provides an ideal material choice for IGBT module housing.
1. High CTI value ensures safety and stability
The CTI value of conventional PPS on the market is only about 170V, which cannot meet the needs of IGBT modules, while NAPO-PPS plastic has been modified with a special formula, and its CTI value is as high as 300-600V, which means that in a high-voltage environment, the surface of the material is not prone to electrical breakdown and has good insulation performance. For IGBT module housings, this high CTI value material selection can effectively prevent electrical failures and ensure the safe and stable operation of the modules.
2. Excellent high temperature resistance
Napo PPS modified plastics have excellent high temperature resistance, can maintain stable physical and mechanical properties in high temperature environments, and are not easy to soften and deform. This makes it ideal for IGBT module housings, which protect the proper functioning of the electronic components inside the module under extreme operating conditions.
3. Excellent chemical resistance
In the automotive operating environment, IGBT module housings need to be chemically resistant and resistant to a wide range of chemicals. NAPO PPS material has excellent chemical resistance, which can effectively protect the internal electronic components of the module and extend the service life of the module.
The excellent performance of PPS plastic provides a reliable choice of IGBT module housing material for new energy vehicle OEMs, and the application of high-performance materials also injects strong impetus into the sustainable development of the new energy vehicle industry.
