Application
The VR2000 MDR Computer Display Moving Die Rotor Rheometer is a precision instrument designed to determine the vulcanization index and viscosity of rubber materials. By applying specific temperature and pressure conditions, the rotor generates a defined degree of rotation, creating shear stress on the sample and measuring the resulting anti-shear torque. This rheometer is essential for quality control in industries such as rubber manufacturing, tire production, and wire and cable manufacturing.
