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
• D71271 Standard test method for viscoelastic properties of paste ink vehicle using an oscillatory rheometer
