Auto Elmendorf Tear Tester (patented product), is used to determine the ballistic tearing strength of textiles, plastics, paper or board.
It enables rapid determination of the dynamic resistance of materials designed to be subjected to strong shearing loads (e.g. fabrics) or liable to be damaged by sharp or heavy objects (e.g. paper bags). Subsequently, the test was naturally adopted for all materials in the form of sheet or films, cardboards, cloth, knitted fabrics, plastic films, aluminium foil, non-woven fabrics, complex flexible packaging etc.
Elmendorf type tear tester is not applied to sparse fabric or stretch materials which the tearing direction might be shift in test.
Compressed air of 0.4~ 0.7Mpa is required.
