1986 Social Text No. 15. 60 To fill the void left by the evanescent traditions of the majority, an ‘artificial’, ‘showy’, ‘complacent’, ‘pseudoplastic’ art is fabricated after degraded models of elite art.

1922 Science 13 Oct. 424/2 Colloidal solutions at different concentrations fall into two types—plastic and pseudo-plastic—between which there seems to be a sharp distinction.

1929 Industr. & Engin. Chem. Nov. 1108/1 The primary difference between pseudoplastic flow and ideal plastic flow is the absence of a real yield value in pseudoplastic flow.

1962 Lancet 15 Dec. 1263/1 The plastic or pseudoplastic flow of abnormally viscous bile caused by metallic ions is converted into a newtonian flow by the action of chelating agents.

1995 Chem. in Brit. Dec. 944/2 Non-aqueous microgels..have been used as additives for conferring pseudoplastic or thixotropic properties to coating formulations.

1929 R. V. Williamson in Industr. & Engin. Chem. Nov. 1108/1 Certain types of dispersions do not flow in accordance with the laws of either ideal fluids or ideal plastics. The flowing properties of such dispersions are similar in many respects to the flowing properties of ideal plastics; therefore we shall refer to them as pseudoplastics.
