The push for rubber compounds with improved characteristics in the rubber industry has sparked extensive research strategies for developing novel rubber compounds with improved properties like tensile strength, abrasion resistance, rolling resistance and flex properties etc., especially for the automobile industry. To intensify the processability, performance, and look of materials such as plastics, rubbers, paints, color, printing, and lubricants, additives are often employed to improve their qualities and overall value during both manufacture and application. The study explores a range of nano additives to enhance the mechanical properties of rubber composites, such as tensile strength, elongation, and resistance to wear, without sacrificing elasticity. Nano additives like calcium carbonate are low-cost additives which show improved flexibility and longevity of the rubber materials.  Incorporation of such nano additives are expected to improve the reinforcing and performance properties like tensile strength, abrasion loss and rolling resistance. Improved rolling resistance is key to improve fuel efficiency of vehicles significantly. This research article is a humble attempt to investigate incorporation of readily available nano material to improvise useful properties, with a focus on cost implications. This paper investigates use of CaCO3 nano additive (BNT900) for improving the physical and cure characteristics of rubber compounds. Overall, this research work provides a valuable insight into the application of CaCO3 nano material in unfilled rubber compounds (without carbon black) to produce rubber materials with improved physical properties.

Keywords: Nano additives, nano CaCO3, reinforcing properties, rubber compounds, SBR.
