Half capillary 2,095 mm / 8 mm
The half capillary is used for polymeric materials with very low viscosity. These materials, which achieve flow indices higher than 80 [g / 10min], will slow down and their testing will be no problem. If you are going to use a half capillary, you need to adjust the capillary plastometer settings and record this change in settings.
