General Properties
Total Thickness
Total Thickness
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.
75 μm
Chemical Properties
Ion Exchange Capacity (IEC)
Ion Exchange Capacity (IEC)
Ion-exchange capacity measures the ability of a material to undergo displacement of ions, previously attached into its structure, by oppositely charged ions. It is measured as the quantity of ions that can pass through a specific volume and a common unit is eq/L.

In the case of an Ion-exchange polymer, it represents the total of active sites or functional groups responsible for the exchange and is the theoretical maximum amount of ions that we can load.
2.3 - 2.6 meq/g
Mechanical Properties
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
30 - 40 %
Tensile Modulus
Tensile Modulus
Tensile modulus is a mechanical property that measures the stiffness of an elastic material. It is the slope of stress / strain curve of a material under direct tensile loading.

It can be used to predict the elongation or elastic deformation of an object as long as the stress is less than the tensile strength of the material. Elastic deformation is caused by stretching the bonds between atoms and the deformation can be reversed when the load is removed.

Tensile modulus is affected by temperature and is an important engineering attribute since we generally want to keep elastic deformation as small as possible.
Tensile Modulus @25°C 300 N/mm2
Tensile Strength
Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can withstand while being stretched or pulled before failure.

Some materials break very sharply, without plastic deformation, in what is called a brittle failure. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture.
Tensile Strength
Tensile Strength
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.
40 MPa
Thermal Properties
Glass Transition Temperature (Tg)
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.

The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.

Additional Information

Non Disclosure Agreement

This is a proprietary product from Ionomr, therefore, we require a signed NDA between the end customer and Ionomr before we are able to ship out the material, either for commercial use, or research.

This is done to prevent reverse engineering and public disclosure. The NDA does not restrict patenting anything, but does include the physical materials and their composition as confidential which prevents specific disclosure in a patent or otherwise but not calling out use of an AEM including Aemion by trade name. The test results are included as confidential information, and require  approval from both parties to disclose. We are not concerned about blocking any publications, but would typically advise if we believe better results can be achieved.

We have a more explicit MTA (Materials Transfer Agreement) we use with academic/research organizations which outlines more detail around materials IP and publication.

Please find the NDA here and fill it in when contacting us for quotations.
