Voice of Customers for VPA

We introduce the opinions and questions from the attendee to a series of our seminars of “Adhesion and Peeling Analysis by use of our Versatile Peeling Analyzer (VPA)”.

I had interests in observing peel behavior in motion. I felt that setting of the instrument and the way of observing were very simple but the instrument presented a lot of information

This is our key concept as a competitive edge.


I would like to have many exact data and consideration on  observation of peel behavior.

We are on the way to develop a sort of Data Bank to pile up various kinds of measurement and would like to introduce more data for customers down the road.


Observation of peel behavior with magnifying camera is useful because we can compare different samples in some points that we cannot figure out from numerical data nor from observation of the interface after peeling. I would like to learn of relationship between peel angle and adhesion as well as test results using samples of curved surface in the future.

We are making careful preparations to test the peel force depended on thickness of backing and curvature of surface. If you have exact samples, you can test them at our lab in Tokyo area.

I had interest in dependency on angle and speed of peel test by VPA because the universal testing machine in our company allows peel tests under 180 degree and 90 degree only. I would like to know the dependency on peel angle and see peel behavior through movies using some different tapes like strong adhesive tape, weak one etc..

We try to pile up test data so that we can introduce more data for customers down the road.                                      

I am not satisfied with the repeatability of the instrument for peel test that we own now and made by other manufacturer. I learned from your product some parameters effective to peel force and considered that they had something to do with the causes of dispersion in data problem that we now have.

(VPA users)
We need the instrument that can control test atmosphere .

We offer the heater type stage set as option that is capable to heat up the peel surface of adherend sample. Atmosphere control devices are available at customization. Please contact us for details.

We have had some problems with adhesion strength of tapes and resin so I had interests in the way of test and analysis of VPA.  It can peel at any angle freely and I felt that the test were very close to real situation.  I had an impression that this company had been developing and manufacturing unique and interesting instruments.

I have been considering that observing peeling behavior is very useful to know physical property of materials and have been searching the possibility to realize that. In this point this instrument caught my interest.  I want to observe the conditions of each materials being peeled off.
I expect your company to develop instruments that enable us to comprehend physical property more accurately as indicator of adhesion.

Sophisticated high speed camera is necessary to observe peel behavior, which is available at customization. Please contact us for details.

I became interested in the function of VPA that observes peel behavior. We can look at the condition that the adhesive tape is being peeled from the substrate from back side of it only if the substrate is glass adherent. I felt it attractive if we could observe it even when a substrate was opaque. If friction coefficient can be measured also by this instrument, I may consider of purchasing it when we need to buy a new peel tester.

We consider that observation of peel behavior on even opaque substrate is possible by changing camera angle. We deal with this camera device and measurement of coefficient of friction by customizing. Please contact us for details.
