The 2000 series (RPA2000, MDR2000, MV2000, etc.) has been on the market for over 30 years. As a result, especially due to the pandemic, the stable supply of parts has become increasingly difficult year by year. In a few years, depending on the parts, there is a possibility that the supply of parts may become challenging. Currently, we are proposing the following: 1) Overhaul of the equipment: Replace only the drive and control parts of the testing machine with new components. 2) Purchase of the following parts: Parts that may become difficult to obtain in the near future.

One of the functions of RPA is the "stress relaxation test" function. Unlike the Mooney viscometer, it allows for stress relaxation tests to be conducted on a single sample after pre-curing, post-curing, and other test conditions. It is known that the relaxation speed and the decrease in torque differ between pre-curing and post-curing. There may also be potential for using it as a reference for tensile testing.

This is an introduction to rheometers for composite materials, thermosetting resins, thermoplastic resins, etc. The maximum testing temperature is up to 350°C, and the die shape is flat type. <Features> - Very easy to handle: Data reproducibility is ensured regardless of who uses it. Not affected by sample shape. - High measurement torque: Capable of measuring greater torque than other companies' high-precision rheometers. - No need for dedicated sample creation: Testing is possible with liquids, pellets, powders, etc. ⇒ Reduces sample preparation time. *The above sample shapes can also be tested with existing RPA2000, MDR2000, Premier RPA, and Premier MDR. <Stress Control Function> *Effective for materials with unknown physical properties!! - Input "stress value" on the testing condition screen. - The device operates automatically based on the stress. - When torque is low: strain is high - When torque is high: strain is low.

Rubber can withstand very large deformations without causing permanent deformation or destruction, making it ideal for many applications such as vibration dampers, seals, and structural bearings. As a result, the concept of predicting the service life of compounds has garnered practical and scientific interest. The service life of rubber compounds defines limits and sets parameters for engineering design. The three main engineering tasks in the application of rubber products are to determine service life and remaining service life. Therefore, predicting service life is clearly of high scientific interest, and a comprehensive lifespan prediction model is needed. One of the main challenges in developing service life models is selecting parameters from materials and usage environments.
