A careful evaluation of a rubber formulation indicated significant enhancements through intelligent incorporation of polyol, hydroxypropyl starch, and ZnO. Initially, difficulties regarding processing plus mechanical behavior were addressed by optimizing each component level. Specifically, polyol functioned as a softener, enhancing flexibility at l

The careful evaluation of the rubber formulation showed significant improvements through intelligent inclusion of polyol, starch ether, and ZnO. Previously, problems related to manufacturing plus performance were mitigated by fine-tuning the component level. In particular, polypropylene glycol served as the softener, improving flexibility at low te
