Specification:
Device Model: Rubber Process Analyzer 2000 (RPA)
Device model: RPA 2000
Manufacturer: ALPHA
Country of manufacture: USA
Software name used: Eclipse
Description of test:
The rheological-mechanical-dynamic measuring device (RPA) can analyze rubber mixtures before, after and during baking without the need to make a sample with specific dimensions and shape, and obtain valuable information about the viscoelastic properties of rubber materials. With this device, the storage modulus, dissipation modulus, Tan D and time torque diagram can be measured for rubber samples.
Available services:
-
Provide graphs of viscoelastic properties as a function of frequency, temperature, time and strain
-
Stress relief test
-
Measuring the properties of rubber mixtures before, after and during baking
-
Determine the time required to reach the desired torque
-
Help determine the formulation and evaluate the rubber compound formulation
Sample preparation:
A volume of 4 to 6 cubic centimeters of the sample is required.
Applicable standards:
-
ASTM D5289
-
D6048
-
D6204
-
D6601
-
D7050
-
D7605
Limitations:
- Measurable frequency range: 50-016 Hz
- Measurable temperature range: from room temperature to 230 degrees Celsius with an accuracy of close to 1.0 degrees Celsius
- Strain applied: 3% to 1250%
