On April 21, 2026, new progress emerges in the polymer processing sector. As the most widely used additive in polymer production, fillers not only expand capacity and reduce costs but also significantly enhance mechanical properties, heat resistance and wear resistance of materials, becoming critical for industrial upgrading. Fillers are available in diverse categories including silicates, carbonates, metal oxides and organics, with granular, powdery and fibrous forms. They restrict matrix molecular chain movement to improve thermal stability and rigidity. Inorganic fillers generate almost no VOC, and high filling ratio lowers product VOC emissions, aligning with eco-friendly trends. Talc powder, widely applied in PP modification, balances performance optimization and cost control. The industry is shifting fillers from traditional filling to functional and green applications. Future focus will be on interface modification and precise proportioning, driving polymers toward high-performance and low-emission development.
