PLASTICS - PREPARATION OF PVC PASTES FOR TEST PURPOSES - PLANETARY-MIXER METHOD
10-01-2019
12-01-2013
Defines two procedures, A and B, for the preparation of pastes (also known as plastisols) from appropriate PVC plasticizers, resins and other ingredients by means of a planetary mixing process. Both methods can be used to prepare pastes of any composition. Method A (single-speed) is particularly applicable to resins prone to heat build-up during paste preparation, while Method B (two-speed) might be preferred for repetitive work, e.g. for process control during resin manufacture, because of its shorter mixing time. Such pastes may be used for a variety of test purposes, including the determination of rheological properties for resin specification and designation.
