It is used to test the bending resistance quality of midsole fiberboard of leather shoes, casual shoes, walking shoes and travel shoes.
The sample is continuously reciprocated and bent 90 degrees to the left and right until it breaks, and the number of breaks is used to determine the bending resistance index of the midsole, which is used as a basis for comparison and selection of the midsole . Sampling requirements: Cut a standard sample with a length of 80mm and a width of 10mm from the finished fiberboard. Result Judgment: The number of times when it breaks is used to judge the bending resistance index of the midsole.
