The thorough assessment of the rubber compound showed significant improvements through strategic inclusion of polypropylene glycol, starch ether, and zinc powder. Previously, difficulties related to processing and physical properties were addressed by adjusting the ingredient loading. Notably, PPG served as a flexibilizer, increasing flexibility at

The precise assessment of a rubber mixture showed notable enhancements through the inclusion of polyol, modified starch, and ZnO. Initially, problems concerning manufacturing & physical properties were mitigated by adjusting individual ingredient concentration. In particular, polypropylene glycol served as the plasticizer, improving flexibility at
