PEEK
PROPERTIES OF PEEK
PEEK has a high tensile and flexural strength, high impact strength and a high fatigue limit. High heat distortion temperature, high chemical resistance and high radiation resistance are also included in the remit of PEEK. Furthermore, PEEK provides good electrical properties, good slip and wear characteristics as well as low flammability.
