Solving the Mystery of Kinking
Test Methods for Characterizing the Flexural Behavior of Plastic Hoses
The flexibility of infusion lines is a key product feature for their application. However, adverse pressure may cause kinking that can interfere with treatment safety. New test methods characterize the kinking behavior of hoses, and are able to predict the behavior over several days within hours.
