Structure and properties of self‐reinforced polyethylene prepared by oscillating packing injection molding under low pressure
1995
This article reports the influence of oscillating pressure on the mechanical performance of general-grade high-density polyethylene (HDPE). The tensile strength of 93 MPa and the Young's modulus of 5 GPa were obtained by an oscillating packing technique. The great improvement of the mechanical properties of HDPE specimens is due to the existence of the shish-kebab crystalline structure, the orientation of the molecular chains along the flow direction, and the more perfect crystallites. © 1995 John Wiley & Sons, Inc.
