A study of free radicals in irradiated/aged UHMWPE materials

UHMWPE bar stock, resin powder and fibers that were irradiated with an electron beam and then stored in air for three years were investigated for long-lived free radicals. Significant concentrations of free radicals were found in all UHMWPE materials. Peroxy radicals are predominant in the UHMWPE ma...
