Operating Principle
The Smart Mooneyline Viscometer determines the Mooney viscosity of rubber and elastomer samples by measuring the torque required to rotate a test rotor within a temperature-controlled material sample.
The measurement is performed under defined temperature and test conditions. The resistance of the material to rotor rotation is recorded as a measure of its viscosity and processing characteristics.
Thanks to the high data sampling rate of its specially developed electronics, time-dependent changes in material behaviour can also be recorded accurately. This enables not only conventional viscosity measurements but also the investigation of stress relaxation behaviour.
Applications
The Smart Mooneyline Viscometer is particularly suitable for:
Quality Control of Rubber Compounds – Evaluating the viscosity and processing characteristics of elastomers and rubber compounds.
Raw Material Characterisation – Investigating the rheological properties of different rubber materials.
Stress Relaxation Analysis – Evaluating time-dependent stress relaxation behaviour for advanced material characterisation.
Production Monitoring – Monitoring consistent material properties throughout rubber manufacturing and processing.
Research and Development – Investigating and comparing different elastomer formulations and material compositions.
Standardised Material Testing – Performing industry-standard test procedures in accordance with ASTM D1646.
The Smart Mooneyline Viscometer provides a powerful and reliable solution for determining Mooney viscosity and comprehensively characterising elastomers. Its combination of robust construction, high-precision measurement technology, high data sampling rates and flexible database connectivity makes it a versatile instrument for modern rubber industry laboratories.
