1Cardboard stiffness testerProduct Overview
ZB-TD500Cardboard stiffness testerIt is an instrument used to measure the bending resistance (stiffness) of paper and cardboard. Design according to the working principle of the universal static bending method.
This instrument is designed based on the principle of static bending, which means that the free end of a specimen clamped vertically is bent. When the specimen reaches a certain bending angle, the resistance is called the bending stiffness, which is measured in units ofmNOr the product of resistance and test length, in units ofmN.m.
