Low Density Polyethylene Particles

Product Safety Features

Extrusion Extrusion is an important processing method for LDPE. Thin pancreas, pipes, sheets, profiles, coatings, wires and cables are all important products processed by extrusion. The resin is melted in the extruder and then fed through the die head. The die head gives the melt the shape associated with the final product. The melt can be drawn into a thin cross-section in an air gap and then cooled and its shape maintained. The solid plastic enters an ejector, which draws the melt out of the die head and through a cooling system, after which the plastic is cut into bundles or rolls of different widths and lengths. Extrusion is a continuously operated process used to produce products with the same cross-section and a certain length.
