RPA
Rubber testing machine cure meter & dynamic viscoelasticity device 'RPA' - A rubber testing device equipped with measurement technology for reproducible data that is available.
The "RPA" is a rubber testing machine equipped with measurement technology that provides accurate, reliable, and reproducible data. With the availability of an automation system, productivity in unmanned labs can be maximized in all testing environments. Additionally, it meets relevant ASTM, DIN, and ISO standards, making it ideal for quality control, analysis, and research. We offer the "RPA elite," which achieves very high accuracy and reproducibility of data, and the "RPA flex," a rotor-less rotational shear hardening measurement device. 【Features】 ■ High-resolution variable direct drive motor for absolute strain control ■ Very robust testing frame for accurate compliance-free data ■ Auto-sampler available for unmanned operation ■ User calibration and user-replaceable seals

Detailed information
-
Isothermal frequency sweep Measuring the viscoelasticity dependent on the frequency of materials is an excellent method for understanding their molecular structure. As shown in the figure, frequency sweeps reveal information about molecular weight (crossover frequency) and molecular weight distribution (crossover elastic modulus).
-
Strain sweep during filler addition Strain dependence is particularly important as an indicator of the quantity and type of dispersion and interaction of rubber fillers. In this example, the effects of five different levels of carbon black addition are observed in the low strain region. High strain behavior generally does not respond to filler addition, as it is less responsive to filler-filler interactions, further dependence on polymer molecular weight, and polymer-filler interactions.
