A thorough evaluation of a rubber compound showed notable benefits through intelligent inclusion of polypropylene glycol, starch ether, and ZnO. At first, problems related to processing and physical properties were resolved by fine-tuning individual component loading. Specifically, polypropylene glycol functioned as a flexibilizer, enhancing low-te

The careful evaluation of the rubber compound revealed significant enhancements through intelligent inclusion of PPG, hydroxypropyl starch, and zinc powder. At first, challenges related to fabrication plus performance were resolved by adjusting each component concentration. In particular, PPG acted as the flexibilizer, increasing flexibility at low
