Sealing profiles, which are indispensable components of automotive vehicles, contain many petroleum-based products which automotive manufacturers are working to replace with biodegradable materials. The aim of this study is to investigate the effect of carboxylated nanofibrillated cellulose (CNFC) on the ethylene propylene diene monomer (EPDM) rubber in terms of evaluation some properties such as mechanical, chemical, thermal, morphological, rheological, and deformation. The CNFC was added at levels of 1, 3, 5, and 10 parts per hundred parts of rubber (pphr) to the EPDM rubber compound instead of synthetic and petroleum-based EPDM to develop CNFC/EPDM green composites. The rheological results showed that the CNFC/EPDM green composites were still acceptable according to the strength specifications of automotive manufacturers. Despite some lower mechanical properties, CNFC addition up to 10 pphr was still a suitable replacement for EPDM because the values were within specifications of automotive manufacturers. However, when the CNFC was added at more than 3 pphr, the lifespan of the CNFC/EPDM green composites was limited to three years according to the weathering results.}, number={4}, publisher={Duzce University}
