The extrusion of cellular polyethylene insulation

$15.00

The effects of certain extrusion variables on the diameter and capacitance uniformity of cellular polyethylene insulation are reported. Melt temperature and head pressure uniformity were varied to produce poor and optimum extrusion quality levels for each of five diverse screw designs. Screw design variables and some common problems in the screws are examined.
