Polymer testing experts at the Applied Technical Services Family of Companies (ATS FoC) and SGS use rotational rheometry to assess how polymer materials respond to applied force and controlled motion. This testing provides valuable insight into viscosity, flow behavior, and viscoelastic properties, which influence polymer processing and performance in final applications.
We offer professional polymer testing services for manufacturers, material suppliers, and research teams. Our laboratories follow established procedures and controlled conditions to generate reliable material data. We support both individual evaluations and comprehensive polymer characterization programs.
What Can Rotational Rheometry Testing Reveal About Polymers?
Rotational rheometry measures a material’s response to rotational movement under defined conditions. Testing examines polymer behavior across various shear rates, temperatures, and other controlled parameters. These measurements help evaluate properties such as:
- Viscosity and flow behavior
- Shear-dependent viscosity
- Temperature-dependent material response
- Storage and loss modulus
- Viscoelastic behavior
- Gelation or curing behavior
- Changes in material structure during testing
These properties help engineers predict polymer behavior during processing and support comparisons between different formulations, grades, or production batches.
How Does Rotational Rheometry Support Polymer Development?
Material behavior varies with temperature, shear, formulation, and processing history. Rotational rheometry offers a controlled method to evaluate these effects. Polymer developers use test data for material selection and formulation studies.
Manufacturers rely on results to investigate processing variations or product performance changes. Quality teams use comparative data to assess materials from different sources. Testing is especially valuable when a polymer must meet specific processing or performance requirements. Rheological measurements offer objective data alongside thermal, mechanical, and chemical characterization.
Who Benefits From Rotational Rheometry Testing Services?

When Should You Consider Rotational Rheometry Testing?
Rheological testing provides valuable information throughout a polymer’s lifecycle. Early testing supports material development and formulation, while later evaluations help investigate manufacturing changes or material differences. Common applications include:
- Comparing polymer grades or formulations
- Supporting new material development
- Evaluating processing characteristics
- Investigating changes in viscosity
- Characterizing temperature-dependent behavior
- Supporting quality investigations
- Generating data for research and engineering programs
Results help identify measurable differences between materials and provide context for findings from other polymer testing methods.
