General Info

EtroX® I CM is a polyimide polymer designed to meet the demanding requirements of the electronics, aerospace, and automotive industries. It maintains high performance under extreme conditions due to its high-temperature resistance and mechanical strength at elevated temperatures. The material offers high tensile strength and dimensional stability, ensuring reliability in demanding applications with strong mechanical properties. 

EtroX® I CM can withstand temperatures exceeding 250°C / 482°F, making it suitable for replacing metals in high-heat environments. Its low inherent flammability is crucial for applications where safety is a priority, reducing the risk of fire. Moreover, it can be precision machined using conventional CNC machines. 

With its low wear rate, it extends the lifespan of components, enhancing overall efficiency and cost-effectiveness in a wide range of bearing and wear applications. This material is used in various industries, including electronics and the semiconductor industry. It is utilized in front-end applications, wafer handling, high and low-temperature operations, and dicing processes. It is suitable for high-strength, high-temperature bearing and wear components, such as thrust washers for electric cars in aerospace and vehicle construction. Furthermore, it is used as test sockets for final chip testing and grippers for glass bottles. Overall, EtroX® I CM is a versatile, high-performance polyimide material offering significant advantages over traditional thermoplastics and metals, particularly in high-temperature and high-strength applications.
