A careful evaluation of a rubber mixture showed notable enhancements through strategic addition of PPG, modified starch, and zinc powder. Previously, challenges regarding fabrication & performance were addressed by adjusting individual component loading. Notably, PPG functioned as the flexibilizer, enhancing flexibility at low temps & lowering form

A careful evaluation of the rubber mixture showed significant benefits through intelligent addition of polypropylene glycol, hydroxypropyl starch, and ZnO. Initially, problems concerning fabrication and performance were resolved by adjusting each component concentration. In particular, polyol functioned as the softener, enhancing flexibility at low
