Nitrogen gas is an inert gas widely used in the plastics industry for various purposes. In LDPE production, nitrogen gas can be introduced during the granulation process to improve certain properties of the resulting LDPE N3 Tea Color Granules. These are typically produced through a process called melt compounding or melt blending. In this process, LDPE resin is melted and mixed with nitrogen gas. The mixture is then solidified into LDPE N3 Tea Color Granules through cooling and solidification processes.
