Na2so4 filler masterbatch is an economical mineral-filled masterbatch developed to optimize production cost while maintaining stable processing performance in plastic products. Manufactured with refined sodium sulfate and compatible PE or PP carrier resins, it offers uniform dispersion, good whiteness, and smooth extrusion behavior. This filler masterbatch is particularly suitable for blown film applications where cost efficiency and surface appearance are important. Different loading levels can be customized according to mechanical and economic requirements.
