ABSTRACT This study introduces an advanced methodology for evaluating the heat‐generation properties of rubber compounds using a process analyzer (RPA). A technique was developed to measure heat build‐up (HBU) by analyzing tan δ under constant energy input. The test conducted in RPA after situ curing within biconical dies, ensuring precise measurement controlled conditions. influence fillers, particularly carbon black (CB) loading and particle size, on HBU examined natural (NR), styrene‐butadiene (SBR), 50:50 NR/SBR blend. values from were compared with standard laboratory methods, including temperature rise (Δ T ) Goodrich Flexometer, dynamic mechanical analysis (DMA), rebound resilience, hysteresis universal testing machine (UTM). strong correlation ( R 2 > 0.9) between RPA‐derived these conventional parameters confirmed reliability proposed technique. statistically validated approach offers efficient accurate method assessing generation compounds, aiding optimized compound design performance enhancement.
