And the way crystals form inside a polymer can completely redefine its final performance. In semi-crystalline polymers like polypropylene and polyethylene, cooling is not just a temperature change; it is a structural transformation. As the melt cools, molecular chains begin arranging into crystalline regions called spherulites. But fillers dramatically influence this process. Talc acts as a powerful nucleating agent. It accelerates crystallization and creates smaller, finer crystalline structures. The result: ✔️ improved dimensional stability ✔️ reduced shrinkage ✔️ higher stiffness ✔️ faster cycle times Calcium carbonate behaves differently. Its nucleation effect is weaker, producing larger and less controlled crystalline morphology. And silica introduces another layer of complexity through strong interfacial interactions that ...
