Our large selection of ePTFE membrane films and laminates solve problems in a wide range of applications, including microfiltration, vent filter and breathers, lab equipment, analysis, wet filtration and crystal wrap.
We also provide custom lamination, pleateable cartridge media and much more. If you have a unique requirement, contact us and we will help recommend a product to suit your application.
Tetratex® Membranes are manufactured from 100% ePTFE polymer resin. Tetratex is dimensionally and chemically stable in almost any chemically aggressive environment and in temperatures ranging from –250°C to +280°C.
Our films are thermobonded to substrates such as polyester and polypropylene and can be treated to repel oils as well as water using our patented oleophobic treatment.
Our films, range in thickness, from 180 to 250 micron with a porosity of 80 to 90% and pore sizes of 0.07 micron to 7 microns.
Bicomponent Laminate
Combining Tetratex ePTFE films with a bicomponent substrate gives customers the opportunity to choose a product that is optimally adapted to many filtration and venting requirements

Benefits of Tetratex Bicomponent Range
Advanced Filtration produces a large variety of ePTFE films to provide the degree of protection, filtration efficiency and gas exchange demanded by various applications.
To improve the process ability and mechanical sturdiness a substrate or support layer is laminated onto the ePTFE
This specific substrate is composed of a combination of different plastic polymers. Together they guarantee easy connection to other materials as well as excellent mechanical resistance in harsh environments
Both layers are bonded without the use of any adhesive, this results in good long term stability and high resistance to solvents
Available in a range of pore sizes from 0.2 to 1.5 microns
