Extrusion Foaming System for Fabricating OpenCell Structure

plastic sheet extruders

Low Density Polyethylene foam of open-cell type was manufactured through extrusion foaming system utilizing a physical blowing agent for the application of sound absorption. For the purpose of enhancing the open cell content, salt powder was blended with LDPE changing the particle and content size. Scanning electron microscopy analysis was completed in order to take notice of the cell morphology. With a check out to characterizing the open-cell framework, open-cell content and expansion ratio had been measured with extruded foams. Finally the effect of formulation and processing parameters on cell morphology was investigated.
