Polyetherimide PEI has outstanding resistance to heat (long-term heat resistance at 180℃), and showed good toughness and rigidity, high hardness, good wear resistance and outstanding performance. So, it is very suitable for use in electric and electronic insulation parts (i.e., the various structural components requiring high strength and stiffness at high temperatures). PEI has been widely used in the field of medical instruments and analytical instruments because of its good hydrolysis resistance. It also has excellent mechanical properties, electrical insulation, radiation resistance, high temperature resistance and wear resistance, and can pass through microwave. At the same time, PEI, as an amorphous material, has good heat insulation due to its ultra-high melting point, and therefore PEI profile can be used as a heat insulation board at the high temperature of 300℃.
