The careful evaluation of a rubber formulation showed important improvements through strategic inclusion of polypropylene glycol, hydroxypropyl starch, and zinc oxide. At first, challenges regarding manufacturing & physical properties were resolved by adjusting each component level. In particular, polypropylene glycol functioned as the plasticizer,

A thorough evaluation of a rubber mixture indicated notable benefits through intelligent incorporation of polypropylene glycol, modified starch, and zinc powder. Previously, challenges regarding processing & mechanical behavior were mitigated by optimizing individual additive loading. Specifically, polypropylene glycol acted as a softener, improvin
