This research investigates the impact of polymer blends on strengthening the characteristics of recycled rubber, with a specific emphasis on enhancing mechanical strength, thermal stability, processability, and durability. The main goals are to assess the influence of different polymer blends on recycled rubber's performance and determine the advantages and drawbacks of these improvements. The study used a secondary data review process to evaluate enhancements in performance indicators such as tensile strength, elasticity, and heat resistance by analyzing previous research and case studies. The main discoveries indicate that combining polymers dramatically enhances mechanical characteristics, heat tolerance, and processing effectiveness, resulting in improved longevity and broader possibilities for using recycled rubber. Higher production costs and quality must be addressed. Environmental issues surround polymer additives. Policy implications include research and development, cost-effective and sustainable polymer production incentives, and regulatory frameworks to standardize processes and ensure environmental safety. Polymer mixing improves performance and sustainability, according to a study. These issues must be addressed by supporting legislation and encouraging the innovative use of recycled rubber.
