Dynamic Interfacial Tension Meter

Dynamic interfacial Tensiometers measure the instantaneous changes in interfacial tension during the formation of bubbles or droplets, reflecting the adsorption kinetics of surfactants at the interface. They are used to monitor processes such as coating wettability, ink spreading speed, and emulsion stability, and to control coating uniformity in printing and papermaking.
Selection
Choose between the bubble or droplet method based on the viscosity of the liquid being tested; consider that the time resolution must match the adsorption speed; the temperature control range should cover the actual process conditions; the sample cell material must be resistant to solvent corrosion; and the data interface should be compatible with existing systems.

Dart impact tester measures the toughness of packaging film.
The dart impact test evaluates the material's resistance to damage under dynamic impact, i.e., its toughness, by allowing a dart to fall freely and strike the packaging film. During the test, different impact energies are simulated by adjusting the weight of the dart or the drop height, and sensors are used to detect whether the film ruptures.
Correlation Analysis between Puncture Strength and Bursting Strength of Paperboard
