Study on tribological properties of UHMWPE irradiated by electron beam with TMPTMA and TPGDA as crosslinking agents

► TMPTMA and TPGDA were blended with UPE in alcohol, respectively. ► Then UPE plates were made by compression molding and EB irradiation crosslinking methods. ► TMPTMA and TPGDA were used to increase the crosslinking density of UPE. ► Wear rate of 100 kGy 1%TMPTMA/UPE is 44.2% of that of 100 kGy UPE.
