The 4 Test Method of High Performance Double Sided Acrylic Foam Tape VHB
During production and research from the adhesive tape manufacturer, in order to guarantee the quality, the pressure sensitive adhesive tape will be experienced some testing, the following parts of the 4 test methods of high performance double sided acrylic foam tape VHB is the example of adhesive tape test for your reference. High performance double sided acrylic foam tape VHB is the type of no carrier adhesive tape, is widely used for Automotive Trim and Interiors, Metal Fabrication, Elevators and Lifts etc.
1. The Test of Adhesion – Dynamic Peeling Strength Test
This is described as the strength under a specific temperature with a specific speed and angle to peel the standard square meters of pressure sensitive acrylic foam tape from a stainless steel, the test is normally made as 90° peeling strength or 180° peeling strength.
2. The Test of Cohesion – Static Shear Strength Test
It is to test the required time when the standard square meters of pressure sensitive acrylic foam tape under a specific temperature slides off a stainless steel after holding a constant weight, the test is normally carried out in 20minutes or 72hours.
3. The Test of Cohesion – Dynamic Shear Strength Test
It is to test the required strength when the standard square meters of pressure sensitive acrylic foam tape under a specific temperature slides off a stainless steel after holding a constant speed.
4. The Test of Initial Tack
Using the method of rolling ball on the inclined surface, When a tiny pressure between the steel ball and the pressure sensitive acrylic foam tape cause them a transient contact, through the adhesion of acrylic foam tape to the steel ball to test the initial tack.
