Öznur Bilge KavacikÖznur graduated from Middle East Technical University in 2018. She completed her Msc in polymer science and technology in 2022 at Kocaeli University, researching the development of self-healing bromobutyl rubber formulations by using nanomaterials and mixing technologies. Öznur has been working as a compound development engineer in the R&D department of Brisa since 2018, developing her expertise in rubber compounding and sustainability solutions.
Development of self-healing butyl rubber formulations
Requirements of the tire industry have determined developments in extending the life of the tire. The effect of temperature and time experimental parameters on the self-healing behavior of bromobutyl rubber (BIIR) in the presence of functionalized silica-based nanoparticles was investigated in this study. The rheological properties of the compounds were determined by moving die rheometer (MDR) and Mooney tests. Evaluation of the self-healing property of rubber compounds was carried out by mechanical and morphological analysis.
