Test Background
If the tensile strength of the tape is not high enough and the elongation at break is not good enough, then the quality of the tape will definitely not pass the test. If poor quality tape is used as insulation, leakage is likely to occur, with disastrous consequences. Therefore, it is necessary to conduct tensile strength and elongation at break tests on adhesive tapes.
The adhesive tape tensile strength test can evaluate the consistency of the adhesive tape tensile strength and elongation at break, and is suitable for comparison of various adhesive tape properties. Zhongke Testing and Reliability Experiment Center has the capabilities of environmental testing and reliability performance testing of various adhesive tapes, and provides professional tensile strength testing services for adhesive tapes.
Scope of tests
According to the base material: it can be divided into BOPP tape, cloth tape, kraft paper tape, masking tape, fiber tape, PVC tape, PE foam tape, etc.
According to the scope of application: it can be divided into warning tape, carpet tape, electrical tape, protective film paper tape, stretch film tape, sealing tape, module tape, etc.
According to market penetration rate: it can be divided into ordinary tape and special tape.
According to the application environment temperature: it can be divided into low temperature tape, normal temperature tape and high temperature tape.
Test method
The two clamps of the tensile testing machine clamp the adhesive tape sample vertically and stretch it until it breaks, thereby obtaining its tensile properties (tensile strength, elongation at break).
Method A: Place the tape between two clamps, with the two clamps on the vertical center line, and apply pulling force at a specified rate until the tape breaks.
Method B: Place the fiber-reinforced tape sample on two cylinders, with the two cylinders on the vertical center line, and apply tension at a specified rate until the tape breaks.
