A very important and still unrecognized problem exists in the field of plastics processing: the influence of lubricants during the processing of rigid PVC. In the study described here, a method for measuring compatibility of lubricants with the help of special equipment was developed. A classification of lubricants available on the market was made as a function of their chemical nature, compatibility and their action on the rheology of polymers. Finally, examples of some practical solutions applied in the development of rigid PVC mixtures and based on the knowledge of lubricants are given.
