Q
Highly-crosslinked UHMWPE
A
Created by irradiating the PE, which prompts free radicals from different polymer sections to combine to form chemical bonds between two polymer chains (cross-links)
5-10 Mrad with either gamma or electrom beam irradiation
Improved resistance to adhesive and abrasive wear
Decreased mechanical properties (toughness, ductility, tensile strength, fatigue strength) when compared to conventional PE
