At it4ip, track-etching technology enables us to manufacture micro- and nano-porous track-etched membrane filters with multiple and varied applications, such as asbestos fibre detection, blood filtration, cancer cell scanning or the synthesis of micro and nano-objects.

Responding to the needs of our customers, our products meet strict quality standards; they are characterised by a precise filtration threshold ranging from 10 nano-metres to several dozen microns, a very small thickness and specific surface properties.

developer, manufacturer and supplier of track-etched membrane

Track-etching technology involves irradiating thin polymer films with energetic particles, leading to the formation of latent tracks which are then converted into regular pores by a specific chemical treatment.  This technology is put into practice in a clean room and is suitable for continuous production in the form of rolls measuring several hundred metres.

With a current production and conversion capacity of 150,000 square metres per year, we deliver a wide range of products to our customers worldwide in the form of rolls, sheets, discs or other forms at their request.  We also offer OEM solutions under their own brand.

For more than 35 years, we have used our knowledge and expertise to serve our customers by developing outstanding products adapted to their needs, and in complete confidentiality.  Our flexibility, responsiveness and production performance are the strengths that make our company successful.
