EtroX® I CM natural - ASTM

PI

The premium product for highly demanding applications

Our premium material EtroX® I CM was specially developed to meet the high demands of the electronics, aerospace and automotive industries. As a pure polyimide, it withstands particularly high temperatures. EtroX® I CM can be used to design components that offer significant advantages over other thermoplastics.

Application Examples

Gripper for glass bottles

In the production of glass bottles, grippers are used to guide the bottles through the process. Compared to conventionally used materials (graphite or brass), grippers made of EtroX® I CM increase the service life of the component. Due to the high resistance to high temperatures and the good stability of polyimides, maintenance time can be reduces, resulting in less production downtime and more efficiency.

Test socket for final chip testing

Electronic components (e.g. chips) undergo a test after manufacture. For this purpose, they are inserted into test sockets made of polyimide, which must have high dimensional stability and durability. Our EtroX® I CM material meets these requirements and offers the additional advantage of a long service life and usability as well as high stability and wear resistance. This rules out contamination of the components through abrasion of the test socket.

Thrust washer for electric cars

Thrust washers made of EtroX® I CM increase the efficiency of motors in electric cars due to their high mechanical strength. Compared with conventionally used steel, our material has a lower density and therefore lower rotational capability. It also withstands high temperatures and does not react with powertrain fluids. Due to its high strength, low wear and outstanding properties, electric motors can be operated efficiently.
