Peel Strength Testing

Peeling strength refers to the maximum force required for peeling per unit width of materials bonded together from the contact surface. It reflects the bond strength of the material. This test is widely used to assess the bond strength of tapes, adhesives, paints and flexible substrates, including rubber, films, biomaterials, dental materials, medical packaging and consumables. As a professional reliability third-party testing organization, T, C&A Lab can perform peel strength tests on a wide range of materials according to ISO, ASTM and other standards. Welcome to contact our experts for consultation.

T, C&A Lab's test methods include but are not limited to

  • T-peel strength test

The T-peel test of flexible material to flexible material bonding is to apply a peeling force on the unbonded end of the sample to cause the sample to peel off along the glue line. The angle between the applied force and the glue line does not need to be controlled. This test method is suitable for determining the T-peel resistance of the adhesive under specified conditions of the adhesive sample composed of two kinds of the same or different flexible materials.

  • 90 degree peel strength test

The stress is applied by the 90-degree peeling method to make the flexible metal test piece produce the force required for a specific fracture rate at the rigid metal plate adhesive joint.

  • 180 degree peel strength test

The 180 degree peeling test is to measure the strength of a standard specimen composed of a flexible material bonded to another rigid material or flexible material at a 180o peeling angle. The commonly used rigid materials are metal, plastic and wood, flexible materials are metal, rubber, fabric, plastic and so on.

  • Floating roller peel strength test

The floating rolling method is used to apply load on the sample to produce the force required for a specific fracture rate at the bonding of the metal.

  • Climbing drum peeling strength test

In aerospace and other industries, metal veneer panels, honeycomb sandwich structures, and rigid foams and other sandwich structures are widely used. The peel strength of the climbing drum can be used to measure the bonding strength between the panel and the sandwich layer, and it can also be used to determine the strength of flexible and rigid materials under the specified conditions.
