摘要：

A novel device to fit on the exit of the ACER capillary extrusion rheometer has been designed to allow the controlled application of hydrostatic pressure to the body of the fluid under test. The rheological properties of the fluid can be examined over a wide range, ambient to 200MPa. This paper will describe the equipment and the effect of hydrostatic pressure and temperature on the flow properties to the various polymer melts, PC, ABS, PP and HDPE. It has been found that for certain of these polymers the effects are significant and should be considered when modeling the fluid in dies and injection moulds.
