A major disadvantage of TPE as compared with conventional vulcanizates is their tension set, which it has now been possible to minimize by post-crosslinking of the elastomer phase. This opens up opportunities for processors to develop further applications for commercially available TPE. Note de contenu : - Crosslinking methods - Successes with UV light and UV additives - FIGURES : 1. Evidence of the increase in the molecular weight of SEBS achieved through sulfur vulcanization as determined by GPC - 2. The decomposition of SEBS as a result of treatment with peroxides is evidenced by the wide mass distribution - 3. First evidence of the minimization of residual strain in SEBS in the presence of the photoinitiator Irgacure 127 - 4. GPC analysis of SEBS provides evidence of the increase in molecular weight achieved with Irgacure 127 - 5. The photoinitiator Irgacure 819 shortens the UV exposure time required by SEBS as compared with Irgacure 127 - 6. UV-induced crosslinking in the presence of Irgacure 819 leads to an increase in the stiffness of SEBS En ligne : https://drive.google.com/file/d/1iSfhsoBSmcoT9QfUZ9XrBkqayerrl5Am/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=24135 [article]
