We used natural rubber SIR 20 technical specified rubber (TSR) reinforced with a nanosilica filler. The results showed that using zeolite modified with magnetite and titanate coupling agent (TCA), which are alternative coupling agents to replace silane coupling agents, and amorphous silica as the filler in natural rubber TSR SIR 20 compounds enhanced the mechanical properties of the TSR vulcanization products. The relationships among the crosslink density, mechanical properties and damping properties were also explored. We also identified that an improvement in the properties resulted from a modification of the white oil softener and filler comprising the zeolite-nanosilica-magnetic blends. The results of magnetically modified zeolite showed that the crosslink density, mechanical properties and damping properties increased significantly. The damping ratio in the sample comprising Si + Fe + Z with or without the white oil softener was higher than that of the other samples herein (ζ > 0.03). Based on this result, a reinforced nanosilica filler with magnetically modified zeolite has the potential to replace carbon black and is applicable to damping devices.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Amorphous silica,Cross-link densities,Damping property,Magnetically modified zeolites,Nano-silica,Nanosilica filler,Silane coupling agent,Titanate coupling agents[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Crosslink density,Damping,Mechanical properties,Nanosilica,Zeolite[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][{‘$’: ‘This work was financially supported in part by the “PDU” program in collaboration with BPKLN of the Ministry of Research and Higher Education of Republic of Indonesia, WCR Research Grant from Ministry of Research and Higher Education of Republic of Indonesia No. 1173/I.C01/PL/2019 and the Research Grant of Institut Teknologi Bandung No. 91 m/I1.C01/PL/2019.
