Transparent blown film masterbatch (Na2So4) is a functional masterbatch made by twinscrew extrusion and granulation of highpressure polyethylene and sodium sulfate as the main raw materials.
This masterbatch is mainly made of high-quality pigments, mixed with carrier resins, dispersants, and special hosts. After pre-treatment and coating, it is fully mixed and extruded into granules
Anhydrous sodium sulfate, whose mineral form is Thénardite, is also called sodium sulfate when it is highpurity and fine particle, and is a crystal composed of rhombic crystal system.
The characteristic of sodium sulfate filling masterbatch is that it is added to PP and PE, and has little impact on the transparency of PP and PE.
