Cambridge Polymer Group has world expert rheologists who can assist in developing the proper test methods for characterizing your material, interpreting your results, and making recommendations for formulation modifications. We have state of the art instrumentation, and develop custom fixtures for project-specific characterization. We work with polymer solutions, melts, colloidal systems, and suspensions. Our scientists have designed tests to track the rheological changes in curing systems, linked rheological behavior to sensory experience data, and used rheological tests to identify the source of issues in processing. We also design custom tests and attachments, including systems for characterizing magneto-rheological fluids.

• Steady rotational shear rheometry
• Dynamic rotational shear rheometry
• Multiharmonic frequency rheometry
• Extensional rheometry

Cambridge Polymer Group has some of the world's leading authorities in extensional rheometry. We have designed and built a Capillary Breakup Extensional Rheometer (CaBER®), which is a rapid and easy method of measuring the extensional viscosity of polymer fluids. Let us help you design an applicable test array to fully characterize your material's response to an extensional flow.

Cambridge Polymer Group also designs filament stretching rheometers (FiSER™).

We perform testing in compliance with the following ASTM standards:

• D4603 Standard test method for determining inherent viscosity of poly(ethylene terephthalate) (PET) by glass capillary viscometer
• D2857 Standard practice for dilute solution viscosity of polymers
• D7271 Standard test method for viscoelastic properties of paste ink vehicle using an oscillatory rheometer
