The global shift towards sustainable energy sources has propelled the popularity of new energy vehicles (NEVs), which rely on electricity or alternative fuels. This transition has introduced new demands for materials used in their manufacturing, with plastics emerging as a critical component due to their lightweight and durable properties. However, traditional automotive plastics fall short of meeting the unique requirements of NEVs, which necessitate materials that are not only lightweight and durable but also resistant to high temperatures and possess superior electrical insulation properties. Such advanced plastics are vital for ensuring the functionality, safety, and efficiency of NEVs.
