Flexibility

Flexibility refers to the ability of a material to resist cracking when bent or stretched. It is evaluated through bending tests, such as inspecting for cracks in coatings after bending on a substrate. This property is applied in coatings, inks, and plastics to ensure that products are less prone to breakage during processing or use.
Selection
When selecting flexibility, consider the material type and actual usage conditions, such as bending radius and temperature. Refer to industry-standard testing methods and match them to application requirements, such as printed materials needing to withstand folding and plastic components requiring the ability to endure deformation.
