New olefinic thermoplastic elastomers for Automotive profilesProperties and Structure of Olefinic Thermoplastic Vulcanizatesand novel uncrosslinked Olefinic Thermo Plastic Elastmer

摘要

This study investigates effect of properties of polymer materials (EPDM and Polypropylenern(I.e. PP)) and morphology on the performance of Olefinic Thermoplastic Vulcanizates (I.e.rnTPV) was modified by varying type of polymer(PP or EPDM) and degree of crosslinking ofrnEPDM rubber. Compression set and mechanical tensile strength increase in degree ofrncrosslinking of EPDM rubber. Also smaller dv (volume-averaged particle diameter)/dnrn(number-averaged particle diameter) ratio of TPV calculated from TEM photograph werernexcellent in the physical properties.
