医疗器械用热塑性弹性体的制备及耐辐照性能
Preparation and radiation resistance of thermoplastic elastomer for medical devices
摘要
Abstract
In this work,a thermoplastic elastomer blend(TPV)with irradiation resistance for medical devices was prepared by the dynamic vulcanization of the blends of brominized poly(isobutene-co-p-methylstyrene)(BIMS)and styrene ethylene butylene styrene copolymer(SEBS).Besides,alkyl phenol disulfide was used as vulcanizing crosslinker and bio-based plasticizer was also added.After irradiated by different doses,basic physicochemical properties,headspace gas chromatography,Fourier transform infrared spectra,thermal stability,dynamic mechanical properties and mechanical properties of irradiated TPV were analyzed.The experimental results indicated that the performance of TPV irradiated within 40kGy dose did not change which met the irradiation resistance requirements of the normal elastomers for medical devices.关键词
