| Abstract: | This study addresses environmental concerns surrounding resource depletion and carbon emissions by investigating sustainable fillers in natural rubber compounds. The primary aim is to reduce reliance on the non-renewable carbon black filler. Various renewable fillers are introduced as partial or whole substitutes for carbon black. Initial inferior in-rubber properties arise due to lower surface area and differing chemistry of the renewable fillers. To enhance performance, promising calcium carbonates and lignin-filled compounds are modified using in-situ coupling agents. Incorporating alpha lipoic acid and a titanate agent improves processing and mechanical properties, even yielding carbon black-comparable performance. Silane coupling agents improved the lignin compounds' hardness and rebound resilience but showed diminished elongation and tensile strength. |
