High density polyethylene extrusion processing methods

Dec 20, 2016

Grade for extrusion production has less than 1 melt index and width to the width of the MWD. In the course of processing, low MI can get proper melt strength. Wide MWD more suitable for extrusion grades because they have a higher production speed, lower die reduce pressure and melt fracture trends.

Many PE extrusion uses, such as wires, cables, hoses, tubes and profiles. Pipe applications range from small section for natural gas yellow pipe diameter to 48in used for industrial and urban clarinet of the thickness of the pipe wall. For concrete for large diameter hollow wall pipe made of storm sewers and sewer pipeline alternatives are rising rapidly.
