Product Description

De Mattia Flex Tester-30 Specimens

Flex testing provides useful information about the durability of treated fabrics and also about the ability of coated fabrics to resist development of cracks, or general mechanical deterioration of the material as a result of a relatively large number of flexes. In this test, the test specimen of specified shape and size are repeated flexed mechanically till the desired number of flexing cycles, or till the material under test fails. The effect of flexing on the test specimens and the number of flexes needed to cause failure give an indication of the quality of coating.

The flexing test may be carried out with the help of a De Mattia Flex Tester, in which the grips are located vertically above each other and have their holding face in one vertical plane. The central grip is moved up and down with the help of a motor to flex the specimens held between it and the upper and lower grips.
