Evaluating rubber viscosity or polymer flow characteristic are critical in production process, it determines the material processibility.
Shimadzu and Ueshima Seishakusho rheology testing system range provides everything you need.
Ideal to evaluate viscosity properties from the relationship to temperature, pressure, and flow velocity, etc, for flowable materials. It demonstrates its power in research and development, production processes, and quality control for various flowable materials such as thermoplastic resins, thermosetting resins, toner, composite materials, ceramics and rubbers.
The FDR (Flat Die Rheometer) measures changes in torque that vary with rubber by oscillation and determines the vulcanization characteristics based on changes in the maximum component entered between the upper and lower dies of a flat plate at a specified temperature, subjected to sinusoidal torsional oscillation. FDR provides a corn drive designed to achieve accurate sinusoidal oscillations and a four-heater drive, achieving high accuracy and reproducibility of the test results.
Measure cure time of rubber the minimum required and effective to control curing process of tyre, belt and rubber vibration isolator. Useful to improve product characteristics such as productivity, energy saving, abrasion resistance and durability.
A thermal diffusion constant by measurement of real-time temperature during curing process using wedge-typed mold having a slope, an equivalent cure time and limiting degree of cure can be determined from an activation energy in advance and a blow limiting point at the internal part of sample after cure.
Automatic Williams Plastometer measures plasticity with the height of a sample at time when the sample loaded between parallel plates, measuring plasticity of the sample. The device is a desktop model. One button to obtain the measurement.
This device is used mainly for measuring the plasticity of silicone rubber.
Automatic DMA was designed to eliminate possible measurement errors and variability by adopting the full automatic system and the unique temperature sensor.
Combine with THERMO JETTER, it can measure viscoelasticity down to -90°C without using liquid nitrogen.
Possible to load 60 max. samples automatically (Option :100 pieces )
Sample chucking, measurement and discharge are automated, and there is no human error. iezoelectric load cell realizes more precise load measurement.
