PREMIER™ RPA

Product catalog summary

Overview: The Premier™ RPA (Rubber Process Analyzer) is a sophisticated instrument designed to measure the dynamic properties of raw elastomers or mixed rubber throughout various stages of curing. It performs multiple tests including cure, temperature sweep, frequency sweep, and stress relaxation tests, enhancing testing accuracy and repeatability.

Features: The Premier™ RPA offers advanced data sampling and processing capabilities. It includes a pressure transducer for additional pressure measurements alongside torque. The instrument supports advanced pre-strain settings and improved frequency and strain sweeps, ensuring precise data collection.

Performance Specifications: The RPA operates within a frequency range of 0.1 to 3000 cpm (0.0016 to 50 Hz) and a temperature range from ambient to 446°F (230°C). It features a maximum ramp rate of 1.8°F/s (1°C/s) and a maximum cool rate of 0.9°F/s (0.5°C/s). The strain range is from ±0.07% to ±1255% (±0.005 to ±90 degrees).

Measured and Calculated Data: The device measures torque, temperature, frequency, strain, pressure, and angle. It calculates parameters such as G’, G”, G*, J’, J”, J*, S’, S”, S*, tanδ, η’, η”, and η*.

Testing Standards: The Premier™ RPA complies with several ASTM standards including D5289, D6048, D6204, D6601, D7050, D7605, and D8059.

Benefits: The instrument's design includes sealed biconical dies and tailored seals to minimize slippage, enhancing repeatability and reproducibility. It supports up to 80 unique sub-tests in a single configuration, facilitating comprehensive analysis. The Premier™ Enterprise™ software organizes data into reports and enables statistical control of manufacturing processes.

Electrical and Physical Specifications: The RPA operates on various voltage settings and requires a minimum air pressure of 80 psi. Its dimensions are 22 in (56 cm) wide, 25 in (64 cm) deep, and 45 in (122 cm) high, with a net weight of 346 lb (157 kg).

Graphical Analysis: The document includes a graph illustrating shear stress versus shear rate, highlighting the determination of long chain branching through LAOS analysis, distinguishing between highly branched, slightly branched, and linear structures.
