Extrusion Rheometry of Fluid Materials

Journal of Dental Research, 1979
A capillary extrusion rheometer was developed and tested using Newtonian oils of known viscosity and seven endodontic sealers. The described ap paratus and technique appear appropriate for com parative assessment of the rheological characteristics of a variety of fluid dental materials.

Extrusion behavior of viscoelastic materials

Journal of Colloid Science, 1950
Abstract The relation between viscoelastic properties and extrusion characteristics is discussed. It is shown that materials characterized by nonlinear deformation-time properties necessarily exhibit a nonlinear relation between volume rate of discharge and pressure in extrusion.

Capillary extrusion of composite materials

Polymer Engineering & Science, 1971
AbstractInvestigations on the extrusion characteristics of composite systems were performed on the Sieglaff‐McKelvey capillary rheometer, with particular emphasis on the characterization of flow instability and “melt fracture” phenomena. The mechanisms of melt fracture appear to be identical for both the filled and unfilled polymers (1.

Extrusion rheometer for characterizing thixotropic materials

Review of Scientific Instruments, 1977
A special form of extrusion rheometer has been developed for characterizing thixotropic pastes and high viscosity materials. It consists of a cylinder with an orifice situated halfway along, and has a piston at each end. In use, a sample plug of material is forced through the orifice at a uniform rate by one of the pistons, and the load required is ...
