It is a high-performance dynamic rotorless rheometer that can be used to test the viscoelastic properties of rubber materials before, during, and after vulcanization. Equipped with multiple testing methods such as frequency scanning, strain scanning, and temperature scanning, it can provide users with data on viscoelastic torque, modulus, dynamic viscosity, etc. Through these testing data, various properties of the rubber material such as viscoelastic characteristics, vulcanization characteristics, and the influence of filling materials on the rubber material can be understood.
Users can arrange the test sequence themselves to understand the various dynamic characteristics of the tested material.
It has a wide range of testing capabilities and can be used to test various types of materials such as raw rubber and mixed rubber. It can also be used for laboratory research and rapid testing.
