The oil derivatives plasticizers are commonly used to achieve better processing and the desired properties of elastomeric blends. Plasticisers based on oil derivatives have a negative impact on the environment due to their production and application. For the above reasons, research has been focused on finding the alternatives of conventional plasticisers, namely from renewable sources. The aim of the study was to determine the impact of sustainable plasticizers on the properties of elastomeric blends based on natural rubber (NR) filled with cellulose (CEL). The effect of low-content polycyclic aromatic hydrocarbon plasticizers – RAE (residual aromatic extracts) and MES (slightly extracted solvate) compared with natural oil plasticizers – linseed oil (LO), rapeseed oil (RO) was investigated. Vulcanisation characteristics, rheological and physical–mechanical properties were studied for prepared NR/CEL blends with different types of plasticisers. Based on the obtained results, NR/CEL blends with linseed oil showed comparable values to the conventional plasticisers. In the case of blends filled with bio-fillers, it is possible to eliminate an ingredient based on petroleum products in order to preserve the possibility of biodegradation.
