The Mooney/ Shearing Disk Viscometer is designed for accurate measurement of viscosity, scorch time and cure rates of the elastomers. Micro Vision Enterprises manufactures Mooney/ Shearing Disk Viscometer. The instrument consists of flat, cylindrical disk, driven by a motor to rotate slowly and continuously in one direction. This disk is embedded into elastomer specimen that is confined in a heated die cavity maintained at specified temperature and kept closed by a specified force. As the disk rotates it experiences a shear strain. This resistance to rotate offered by the elastomer is shearing viscosity which is proportional to mean absolute viscosity of the specimen.
Micro Vision Enterprises, an ISO 9001:2000 certified company is the manufacturer of Oscillating Disc Rheometer, Moving Die Rheometer, Mooney Viscometer Dispersion Analyzer, Ozone Test Chamber and Tensile Testing Machine Instruments for Rubber Industry. In Mooney/ Shearing Disk Viscometer, normally a preheat period is given to the elastomer following which the disk starts to rotate. An initial high viscosity is recorded and then as the viscosity also decreases, to a minimum value Viscosity obtained with large rotor are approximately twice those of small rotor.
