General Characteristics of Imidized Materials Best physical properties above 500ºF Best temperature resistance High temperature, high load bearing and wear capabilities (bearing grades) Good chemical resistance Imidized materials are high performance plastics with a high service temperature. These can be considered for applications with an approximate maximum temperature of 500°F. Selecting a plastic material for use in a high temperature environment requires careful review of material properties data. View our interactive Thermoplastics Triangle to compare materials.
