Extrusion Foaming System for Fabricating OpenCell Structure

single screw extruder

Low Density Polyethylene foam of open-cell type was manufactured through extrusion foaming system utilizing a physical blowing agent for the use of sound absorption. For the intended purpose of boosting the open up cell content, salt powder was blended with LDPE changing the particle and content size. Scanning electron microscopy examination was completed in order to observe the cell morphology. With a look at to characterizing the open-cell framework, open-cell expansion and content material ratio had been measured with extruded foams. Finally the result of processing and formulation parameters about cell morphology was investigated.
