The polypropylene\/ethylene\u2013propylene diene terpolymer blends with mixing ratios of 80\/20, 50\/50, 20\/80 were prepared in an internal mixer at 165\u00b0C and a rotor speed of 50\u2009rpm\/min followed by compression molding. The blends and the individual components were radiated using 3.0 MeV electron beam accelerator at doses ranging from 0 to 100\u2009kGy in air and room temperature. All the samples were tested for tensile strength, elongation at break, hardness, impact strength, and morphological properties. After exposing to 25 and 100\u2009kGy radiation doses, 50% PP blend was selected for in vivo studies. Results revealed that radiation-induced crosslinking is dominating in EPDM dominant blends, while radiation-induced degradation is prevailing in PP dominant blends. The 20% PP blend was found to be most compatible for 20\u201360\u2009kGy radiation sterilization. The retention in impact strength with enhanced tensile strength of 20% PP blend at 20\u201360\u2009kGy believed to be associated with increased compatibility between PP and EPDM along with the radiation-induced crosslinking. The scanning electron micrographs of the fracture surfaces of the PP\/EPDM blends showed evidences consistent with the above contentation. The in vivo studies provide an instinct that the radiated blends are safe to be used for healthcare devices.<\/jats:p>","DOI":"10.1177\/0885328217750476","type":"journal-article","created":{"date-parts":[[2018,1,4]],"date-time":"2018-01-04T15:46:32Z","timestamp":1515080792000},"page":"1049-1062","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["E-beam sterilizable thermoplastics elastomers for healthcare devices: Mechanical, morphology, and in vivo studies"],"prefix":"10.1177","volume":"32","author":[{"given":"Ananad Bellam","family":"Balaji","sequence":"first","affiliation":[{"name":"Faculty of Engineering, Department of Chemical and Environmental Engineering, University of Nottingham Malaysia Campus, Semenyih,  Selangor, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chantara Thevy","family":"Ratnam","sequence":"additional","affiliation":[{"name":"Radiation Processing Technology Division, Malaysian Nuclear Agency, Bangi, Selangor, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0265-4820","authenticated-orcid":false,"given":"Mohammad","family":"Khalid","sequence":"additional","affiliation":[{"name":"School of Science & Technology, Research Centre for Nano-materials & Energy Technology, Sunway University, Subang Jaya, Selangor, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rashmi","family":"Walvekar","sequence":"additional","affiliation":[{"name":"Energy Research Division, Taylor's University, Lakeside Campus, Subang Jaya, Selangor, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,1,3]]},"reference":[{"key":"bibr1-0885328217750476","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0274(200101)39:1<100::AID-AJIM10>3.0.CO;2-Q"},{"key":"bibr2-0885328217750476","unstructured":"Marketsandmarkets.com.
