Radiation induced free radical stability and degradation behavior in GUR resin and 1900 resin types UHMWPE over 20 years of aging

Abstract Radiation-induced free radical stability was evaluated using Electron Spin Resonance (ESR) for two medical-grade Ultra High Molecular Weight Polyethylene (UHMWPE) resins, GUR 4150 and 1900H, after 20 years of aging in air and vacuum at 23 °C, 37 °C, and 75 °C. Spectral a...
