adhesion strength 90 degree peeling test fixture

ASTM D3330

Adhesion strength 90 degree peeling test fixture is a professional device used to measure the peel strength of adhesives at a 90° angle. It evaluates the resistance of the bonded interface to peeling by simulating a vertical peeling scenario. It tests the adhesion of tape or materials when peeled vertically and is suitable for bonding tests of rigid materials (such as PCBs) and flexible materials (such as copper foil circuits). 

General introduction

Adhesion strength 90 degree peeling test fixture is a professional device used to measure the peel strength of adhesives at a 90° angle. It evaluates the resistance of the bonded interface to peeling by simulating a vertical peeling scenario. It tests the adhesion of tape or materials when peeled vertically and is suitable for bonding tests of rigid materials (such as PCBs) and flexible materials (such as copper foil circuits). 

With the electronic universal testing machine, it can automatically calculates the maximum/minimum peel force and average peel strength.


Testing the peel strength of bonded materials is one way to evaluate their adhesiveness. The peel strength is determined by applying a constant shear stress to the materials and calculating the resulting force multiplied by the bond surface width. Testing typically entails separating either two bonded flexible materials or a single bonded flexible material affixed to a stiff substrate.

Tape, adhesives, and flexible substrates like rubber, films, biomaterials, consumables, medical packaging, and more are often subjected to peel strength tests to describe their bonding strength. Various peel testing methods are available for a variety of materials. 

90°-peel strength testing
The 90-degree peel test is a method for calculating the unit force required to tear apart bound materials at a 90-degree angle. It can be used to examine the binding between a flexible material and a hard substrate.
