The global electrical industry is looking for sustainable materials in various domains, including electrical insulation cable materials. Tin dioxide (SnO2) nanoparticles combined with deproteinized natural rubber (DPNR) have the potential to produce an excellent and green electrical insulation material that combines their parents’ electrical properties. Yet, the processability is highly influenced by the curing system. The cure characteristics of rubber nanocomposites were investigated for the influence of different accelerators and SnO2 content. The 2,20-dithiobis (benzothiazole) (MBTS)-cured compounds exhibit ultrafast curing and higher melt viscosity than the N-Cyclohexyl-2-benzothiazole sulphonamide (CBS)-cured nanocomposite compounds, regardless of the increment in SnO2 loadings. Therefore, CBS-cured nanocomposites exhibit acceptable process safety, good processability and properties. The morphological, thermal and compositional analyses further supported the density, swelling behaviour and hardness of the DPNR nanocomposites of the selected accelerator system.
