The unique design includes an ultra-rigid test frame, direct drive motor, precision temperature control with optional cooling and intuitive Scarabaeus Software...

The MV one Mooney Viscometer is a fully-featured instrument incorporating the latest technology for traditional Mooney testing. It is configured for standard viscosity, scorch and stress relaxation testing of rubber polymers and compounds under isothermal test conditions at constant speed of 2 rpm. A continuously variable motor mode allows tests over a speed range of 0.1 to 10 rpm. The MV one Mooney Viscometer is equipped with low mass rotors that meet all relevant ASTM, ISO, and DIN standards. All TA Instruments rubber testing instruments are constructed on ultra-rigid test frames and include...

TECHNOLOGY RUBBER TESTING Direct Drive Motor Powerful direct drive motors apply precise deformation in all TA Instruments rubber rheometers and viscometers. A high quality rheological or dynamic measurement relies on the precise application of a constant rate, step, or periodic deformation. In a direct drive system the start-up delays, compliance, and translational losses seen in clutch or belt-driven configurations are eliminated. The superior TA Instruments motor design TA Instruments is the world’s leading supplier of analytical instrumentation for the measurement of viscosity and viscoelastic...

The dies are constructed from durable, applies up to 8 bar nominal pressure to the sample during gap closure. Proper alignment high-stiffness, low thermal expansion stainless steel to minimize system...

TEST FIXTURES RUBBER TESTING VS VOLUMETRIC SAMPLE CUTTER Rotorless Rheometer Sample Preparation RPA and MDR die surface features an optimized arrangement of radial serrations Sample preparation for RPA, MDR, and Mooney instruments is made safe and simple to guarantee constant sample contact at even the highest strain values. Polyester or with the VS Volumetric Sample Cutter. This dual-action pneumatic system allows for the polyamide films may be used to facilitate sample release and avoid the need to clean dies between experiments. preparation of uncured rubber specimens of a user-defined volume....

RELIABLE AUTOMATION An automated film transfer system removes the previously tested specimen and advances the film roll to prepare for the next experiment. An integrated sensor alerts the operator at the end of the roll so it can be replaced in a timely manner. TA Instruments rotorless curemeters and rheometers are compatible with the highly reliable rubber automation system. This carousel-based autosampler allows for the unattended testing of rubber samples. Coupled with the Scarabaeus Software automated analysis, statistics, and control chart generation, the automated rheometer becomes a highly...

ADT AUTOMATED DENSITY TESTER Density testing is made simple with the TA Instruments fully Automated Density Tester. This fully programmable, automated system measures the density of cured rubber materials using the finite difference (buoyancy) method. Active measurement of the fluid temperature increases accuracy by accounting for small changes in the density of the immersion fluid with temperature. Walk-away Automation Sequential, reliable, and unattended density measurements are made using an automatically fed sample tray with 20 or 30 sample capacity. This true walk-away automation is enhanced...

AHT AUTOMATED HARDNESS TESTER The AHT Automated Hardness Tester streamlines the measurement of Shore A hardness for cured rubber materials. This fully programmable, automated system measures the hardness of cured rubber materials according to all international standards for Shore A hardness. Each measurement involves the determination of a user-defined number of single point Shore A values. The individual readings, mean and median of this set are reported for each sample. Reliable Automation An automatic sample feed with 20-sample capacity provides sequential, reliable, unattended measurements....
