What is the tear resistance testing

Tear resistance can be impacted considerably by the speed of the test, e.g. test speed used in generate the tear. Tear propagation resistance for the purpose of acceptance testing is common with materials such as paper and rubber. Tear resistance in textiles involves the load required to propagate a single "rip-tongue" type of tear (tear coming from a cut).

What is the Elmendorf tear tester

Elmendorf tear tester enables rapid determination of the dynamic resistance of materials designed to be subject to strong shearing loads or liable to be damaged by sharp or heavy objects . The tear test was adopted for all materials in the form of sheet or films, cardboard, cloth, knitted fabrics, plastic films, aluminum foil, non-woven fabrics, complex flexible packaging, etc.

GESTER provide elmendorf tear resistance testing.GESTER have the great R&D strength of products and great production capability

GESTER Elmendorf Tearing Tester is designed for tearing resistance test of textile, non-woven fabrics, paper, paper board, thin film, ventilation tape, metal sheet materials and etc.
