Processing toughening agents are indispensable functional additives in the production of PVC products, playing a vital role in improving processing techniques and enhancing product performance.

Main functions include:

Optimizing Processing Performance
Processing toughening agents significantly enhance the rheological properties of PVC melt by reducing melt viscosity and increasing melt strength. This not only improves extrusion speed and reduces energy consumption but also ensures more stable product formation and minimizes surface defects.

Remarkably Enhancing Toughness
By forming a unique sea-island structure, processing toughening agents effectively absorb and disperse impact energy, multiplying the material's impact strength and significantly improving the impact resistance and durability of PVC products.

Improving Overall Performance
While enhancing toughness, processing toughening agents also contribute to better surface quality of the products and promote the dispersion of other additives, resulting in comprehensive improvements in both mechanical strength and appearance.

The application of processing toughening agents enables PVC products to maintain excellent processing performance while achieving superior mechanical properties and broader application fields.
