AB  - Sustainable material development is one of the most researched topics in the automotive industry. 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.

N2  - Sürdürülebilir malzeme geliştirme, otomotiv endüstrisinde en çok araştırılan konulardan biridir. Otomotiv araçlarının vazgeçilmez bileşenleri olan sızdırmazlık profilleri, otomotiv üreticilerinin biyolojik olarak parçalanabilir malzemelerle değiştirmek için çalıştığı birçok petrol bazlı ürün içerir. Bu çalışmanın amacı, karboksile edilmiş nanofibrile selülozun (CNFC) etilen propilen dien monomer (EPDM) kauçuğunun mekanik, kimyasal, termal, morfolojik, reolojik ve deformasyon gibi bazı özelliklerinin değerlendirilmesi üzerine etkisini araştırmaktır. Çalışmada öncelikle CNFC, CNFC/EPDM yeşil kompozitleri geliştirmek için sentetik ve petrol bazlı EPDM yerine EPDM kauçuk bileşiğine 1, 3, 5 ve 10 (pphr) seviyelerinde eklenmiş olup reolojik sonuçlar, CNFC/EPDM yeşil kompozitlerinin otomotiv üreticilerinin mukavemet spesifikasyonlarına göre hala kabul edilebilir seviyede olduğunu göstermiştir. Bazı düşük mekanik özelliklere rağmen, 10 pphr'ye kadar CNFC ilavesi neticesinde, değerler otomotiv üreticilerinin spesifikasyonları dahilinde olduğu için EPDM için uygun bir alternatiftir. Ancak CNFC'nin 3 pphr'den fazla ilave edilmesi durumunda, iklimlendirme koşullarına dayanıklılık sonuçlarına göre CNFC/EPDM yeşil kompozitlerin ömrü üç yıl ile sınırlı kalmaktadır.
