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.

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.

1) Regarding temperature calibration addition As a standard, temperature calibration is conducted at 177 degrees. It is optional, but additional temperature calibration for up to 4 points is also possible. Testing is conducted at several different temperatures, and if data reliability is a priority, we strongly recommend considering additional temperature calibration. 2) Regarding data backup Predicting computer failures is extremely difficult. Have you been backing up the data that has been tested so far? If data preservation is necessary, we kindly ask that you perform regular data backups. 3) Regarding recommended regular inspections We offer three types of maintenance contracts based on customer requests. We recommend entering into a maintenance contract for maintaining data reliability, preventing sudden failures, and for regular calibration of detectors. 1) Maintenance contract programs 1. Alpha Care Simple: Annual inspection 2. Alpha Care Select: Biannual inspection (includes torque standard calibration: a great deal!!) 3. Alpha Care Advantage: Quarterly inspection (includes torque standard calibration and film: even better deal!!!)

The Premier RPA rubber processing analysis device and the Premier MDR vulcanization testing machine are equipped with pressure measurement as standard.

As an addition to the existing Premier RPA product line, we have launched Premier RPA Sub-Zero TechnologyTM. It allows for low-temperature (below 0°C) testing of unvulcanized rubber using the same methods as the previous Premier RPA. This enables testing of vulcanization properties, rolling resistance, wet performance, and more, all with a single device. Additionally, since it does not require the use of liquid nitrogen, running costs can be significantly reduced. <Features> - Customers using RPA will find it easy to handle as it operates in the same way as before. * Temperature sweep tests, strain sweep tests, etc., are possible. - No need to create samples for dynamic viscoelasticity testing ⇒ Time savings. - Automatic sample transport can be installed ⇒ Improved work efficiency. - No need for liquid nitrogen ⇒ Reduced running costs and enhanced safety.

In implementing quality control, the sulfur testing machine alone is insufficient, and the rubber processing analysis device (RPA) is multifunctional and expensive, which has led to the recent customer demand for the commercialization of "Premier MDR+." This device is capable of conducting four types of tests based on ASTM standards. We would appreciate it if you could contact us for more details.

It is possible to enhance the cooling function of existing equipment. This can be achieved by installing a jet cooler onto the cooling hose line of the existing die. The cooling temperature can be lowered to between 15°C and 20°C (depending on the temperature of the supplied air).

Compared to the conventional machine (MV2000), the new model features a standard stress relaxation test and a variable rotor speed. A comparison of specifications with the MV2000 is shown in Figure 1, which can be used for your consideration of an upgrade. <Introduction of Possible Tests> 1) Tests using the variable rotor speed function - Rotational speed: 0.1 to 20 cpm - Detects differences in raw materials with the same Mooney value at 2 cpm 2) Stress relaxation test - Detects differences in processability of raw materials with the same Mooney value

This time, we would like to introduce our sample cutter. We assume that customers with a high number of tests are struggling significantly with cutting samples. Our company sells a punch-type sample cutter as shown in the diagram. Feature 1: Safe and quick sample cutting When using scissors to cut samples, prolonged use of the same task can lead to decreased grip strength and concerns about injuries. However, by using this machine, you can improve work efficiency and enhance safety measures. Feature 2: Improved reproducibility of data It cuts sample quantities uniformly. Therefore, it also addresses data variability issues. *There are two types available: one for RPA/MDR and one for Mooney viscometers. We would be grateful if you could contact us when considering a purchase.

Introducing the Premier RPA rubber processing analysis device. Compared to the conventional model (RPA2000), the optional specifications of the RPA2000 have been upgraded to standard specifications in the Premier RPA. When updating to the Premier RPA, tests that were previously impossible will now be possible. Attached is a comparison of specifications with the RPA2000, which you can use for your consideration of the update. <Introduction to tests possible with RPA> 1) Temperature dispersion test: A function that cannot be performed with a vulcanization testing machine. - Testing can be conducted while increasing or decreasing the temperature. - Data on the temperature-dependent changes in Tan δ (light green in the right diagram) can be obtained. 2) Pain effect test (ASTM D80529) (strain dispersion test): This checks the state of the mixing. - Differences in the state of mixing can be evaluated with uncured samples. - There is a possibility of omitting other tests.

If it has been more than two years since the installation of the device or since the last inspection, we recommend a regular inspection. In the regular inspection, in addition to checking the equipment, we will also clean the die, the area around the die, and the upper part of the motor (a place where rubber debris tends to accumulate). In particular, if you are using the RPA2000 or Premier RPA and have been testing with significant strain, rubber debris is likely to accumulate on the upper part of the motor. If regular cleaning is not performed, it can lead to malfunctions, so we recommend inspections for customers who have not had one.
