Resumen

This study investigates the performance of NR–SBR (80/20) rubber composites reinforced with Carbon Black N330 for use in industrial track pad applications. Five formulations containing 65, 70, 75, 80, and 85 phr of carbon black were prepared and evaluated. Mechanical properties such as hardness, tensile strength, elongation at break, abrasion resistance, and dynamic behavior were measured according to relevant ASTM standards. In addition, field testing was conducted using a tracked vehicle over a 15 km route to assess real-world wear behavior. The results show that carbon black content significantly influences stiffness, strength, and abrasion resistance. Among all formulations, the 75 phr compound demonstrated the best balance of hardness, tensile strength, and wear performance, making it a suitable candidate for industrial track pad applications. These findings provide useful insights for developing locally produced rubber composites with improved durability and cost efficiency.
