概要

The hydrafilm extrusion of high-density polyethylene (HDPE) is investigated and its behavior is compared with that of pure hydrostatic extrusion at extrusion ratios up to 11 and temperatures up to 100℃. Because of the use of a minimum amount of oil as lubricant and pressure-transmitting medium in hydrafilm extrusion, a serious problem of instability or stick-slip phenomena in the polymer extrusion was experimentally proved to be minimized. Also studied was the effect of the extrusion rate, which became more notable with the increase of the extrusion ratio. Billet temperature rise was found to affect the extrusion behavior to a great extent. The range of the extrusion rate for stable extrusion is delineated for a given value of the extrusion ratio.
