Mooneyn.
/ˈmuːni/, U.S. /ˈmuni/ Materials Science.
attributive. Used with reference to various concepts relating to the measurement of physical properties of rubber and other elastic solids, and instruments employed in such measurement; Mooney material n. [described in Jrnl. Appl. Physics (1940) 11 582-92] a material (such as rubber) whose behaviour under large elastic deformation approximates to that of an ideal, perfectly elastic material which is isotropic and incompressible. Mooney viscometer n. [described in Industr. & Engin. Chem. (1934) 15 Mar. 147, where Mooney calls it a plastometer] a type of viscometer for measuring the viscosity of unvulcanized rubber.

1953 Science 6 Mar. 250/2 For rubber broken down in a Brabender plastograph the Mooney viscosity is a semilogarithmic function of the masticating time.
1963 H. G. Jerrard & D. B. McNeill Dict. Sci. Units 90 Mooney Units. The plasticity of raw, or unvulcanized, rubber is sometimes given in terms of the torque on a disc situated in a cylindrical vessel containing rubber at a temperature of 100°C.
1972 Materials & Technol. V. xiv. 500 The Mooney viscometer is most widely used in the rubber industry. It consists essentially of a rotor in a stator chamber, between which a rubber sample is sheared.

1989 Q. Jrnl. Mech. & Appl. Math. 42 271 We remark that for the neo-Hookean material..or for the so-called extreme Mooney material..we need only use one form of the deformation at the outset.
1995 Exper. Techniques 19 24/2 The popularity of the Mooney model..stems from the fact that the form of the strain energy density function is simple, and..involves only two open parameters (materials constants).
