Recently, breakthroughs have been made in the surface activation technology of talc powder, effectively solving pain points such as poor compatibility, uneven dispersion, and degraded mechanical properties between traditional fillers and organic polymers, providing efficient solutions for plastics, rubber, coatings and other industries. Talc powder is naturally hydrophilic, resulting in weak bonding with hydrophobic matrices. Direct filling often leads to soft products and insufficient strength. Activation treatments use coupling agents like titanate, silane, aluminate, or organic polymer coating to convert particle surfaces from hydrophilic to hydrophobic, enhancing interfacial adhesion and dispersion. The complete process includes pretreatment, precise modifier dosing, high-speed mixing coating, and quality testing via activation index and oil absorption value. It significantly improves composite rigidity, strength, heat resistance and dimensional stability, balancing stiffness and toughness while optimizing injection molding performance. This reliable technology meets high-end material demands, driving mineral fillers toward high-value and functional applications.
