Creep Behavior of PA6/NBR TPVs

摘要

The influence of compatibilizers and other additives in PA6/NBR blends is evaluated in terms of creep resistance. The results obtained are correlated with density, selective solvent extraction, tensile strength, DMA analysis, and scanning electron microscopy. Our studies show an enhancement of dimensional stability of samples with the presence of EVAMA in the PA6 master batch. On the other hand, better elastomeric behavior is achieved with the compatibilization process, oxazoline-modified NBR being the best compatibilizer. Also, the possibility of evaluating a material in conditions near to final applications, through a shot-time test, with minimal material waste is shown.View full textDownload full textKeywordsCreep, Mechanical properties, NBR, PA6, TPVRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/1023666X.2010.493269
