Applications

We would like to brighten your future
with our membrane Miraim®.

Teijin has developed a microporous polyethylene membrane.
By combining the polymer and filmmaking technologies
it has cultivated over many years.
And we named it Miraim®, with the goal of it becoming a "membrane".
That will create the future (future is called "mirai" in japanese).

We have developed a delicate membrane.
It has uniform nano to submicron pore size,
and pursues high porosity and extremely thin.

By utilizing this know-how, it is possible to control the pore size and thickness, etc,
based on your needs.

Recently, it is said that alternatives to PFAS materials might be needed,
Miraim® could and an excellent solution to support the environment.

Could Miraim® contribute to your future ?

Forever Chemicals, challenge for PFAS^* issue.
Environmentally friendly PFAS-free^*2 polyethylene porous membrane

Not contain PFAS (perfluoroalkyl and polyfluoroalkyl Substances) in raw materials.

Per- and Polyfluoroalkyl Substances

PFAS are used for a variety of purposes due to their high functionality, but it is said to hard decomposision in nature and remain in the environment for long periods of time once discarded, which is why PFAS are also known as "forever chemicals".
In addition, it is rarely metabolized when taken into the human body, and it has been suggested that it may cause various health problems.

Could Miraim® contribute you want and our planet for future ?
