The rubber process analyzer is an extremely important tool for product research and development across every industry that uses rubber materials. The RPA measures the viscoelastic properties of both polymers and elastomeric compounds. Data is gathered before and after cure. This test method informs production decisions by providing precise information about your sample, like its processability, cure characteristics and speed, and after-cure behavior.

Together, we can increase the quality of your product while increasing production efficiency. Its testing capabilities and the data drawn from those tests are also versatile. Working with our responsive and expert staff members, you can design a course of testing that is tailored to your distinct goals and challenges. This test method measures the viscoelastic properties of both raw rubber and uncured rubber compounds. To measure these properties, ASTM D involves the use of a rotorless oscillating shear rheometer, which measures the flow properties of raw rubber and unvulcanized rubber compounds.

We can measure these qualities with a frequency sweep, a strain sweep, a temperature sweep, or with a timed test. Measurements may be taken at multiple temperatures to produce a range of characteristic data.

The method also covers specified cure conditions comparable to static cure in order to minimize effects on the dynamic properties of cured rubber compounds. This test method is used to determine the vulcanization characteristics of rubber compounds. This determination occurs under selected test conditions designed to simulate the manufacturing process, which will depend on your material, your manufacturing process, and the goals of testing.

The test conditions will not affect the cured dynamic properties of your sample, therefore ensuring test results are consistent and applicable to real-life use.

ASTM D first measures the viscoelastic properties of a sample at an elevated cure temperature, measuring its properties as the material cures. This first sweep measures strain softening and material interactions.

After a predetermined cure time, the test method then also measures the dynamic properties of the vulcanizate at a temperature significantly lower than the cure temperature.

This second sweep determines the breakdown of polymers and fillers caused by the first sweep. Measurements taken at these low temperatures during the second sweep effectively relate to rubber product end-use service conditions, and are therefore useful for research and development. The temperature conditions during testing can be tailored to produce results most relevant to your industry, product development goals, and product end-use.

This test method reveals the viscoelastic and flow properties of raw rubber and unvulcanized rubber compounds. This method may also be used for quality control and research and development. ASTM D is appropriate for rubber compounds containing curatives. This method is also useful if you are interested in evaluating the differences in cure and dynamic properties when using different compounding ingredients.

ASTM D is not recommended for compounds based on silicone or fluoroelastomers, which due to high levels of thermal contraction or poor adhesion may slip during parts of the testing process.

This slippage causes results to be unreliable, so an alternative course of testing is recommended. At ACE Products and Consulting, we understand that the research and development and quality control processes can be daunting.
