Fifty-one years ago, GE Company of the United States began to study this special material. After 10 years of hard work, it finally began to sell it to the market in batches under the brand name GE Ultem 1000F, which is now the PEI material we are familiar with.
Let us uncover the characteristics of this special material, PEI is characterized by high strength, high rigidity, wear resistance and dimensional stability at high temperatures, 1. High temperature resistance (HDT exceeds 200 °C, UL continuous application temperature exceeds 170℃), and the combustion level reaches UL94V-0, so this material is also widely used in aerospace, military and other parts.
This super-engineering material also has exceptional chemical resistance. Its hydrolytic stability is very good, after soaking in boiling water for 10,000 hours, the tensile strength remains more than 85%, and at 270F, the tensile strength remains at 100% after 2,000 cycles of steam hot pressing
If your product needs to be exposed to the sun for a long time, don’t be afraid. Polyetherimide has good UV and Y-ray resistance. It is processed under 400 Mrad cobalt ray radiation, and its tensile strength remains 94%.
In addition to aerospace, military, electronic equipment, and other fields, PEI is widely used as handles, trays, fixtures, prosthetics, medical lamp reflectors and dental appliances for medical and surgical instruments because of its excellent hydrolysis resistance.
The following are some PEI materials produced by our factory, if your products also need to use this super engineering plastic, please contact us. Make your designs come true!
