Low viscosity fluid with a high-shear environment for spray application can be tested with an Instron CEAST SR20 capillary rheometer.
With a CEAST SR50 Capillary Rheometer, Instron was able to test silicone materials to determine which can undergo extrusion at room temperature, observing ISO 11443.
Testing with CEAST Capillary Rheometers and Visual RHEO Software allows manufacturers to understand the change in polymer viscosity related to time.
To ensure sports goggles have correct visual, mechanical, and thermal properties, check the injection of mold plastic components with a CEAST SmartRHEO machine.
To test the quality of un-vulcanized rubber, use a CEAST SR20 capillary rheometer to measure its behavior at different temperatures, pressures, and shear rates.
