TRAKETCH^®: The TRACK-ETCHED MEMBRANE made by SABEU

TRAKETCH^® ion-track membranes are used for cultivating lung cells and tissue. Unlike membranes with a sponge-like structure, they do not let cells sink into the material and adhere to pores but grow where they are supposed to: on the extremely smooth surface of our microporous membranes. Without causing damage the tissue can be easily peeled off for inspection or further use. This principle is also beneficial for cultivating skin cells that are used in transplantations. Another field of application is within the cosmetic and pharmaceutical industries where skin models grown on track-etched membranes can partially substitute ethically controversial animal experiments.

The aim for automotive OEMs using sensitive electronic and other complex components is to increase their lifespan. TRAKETCH^® ion-track membranes have IP ratings of 67 or 68 (International Protection, also known as Ingress Protection) and with their exactly defined pores, they became an ideal protection by retaining liquids and particles for these mechanical and electrical components. In parallel the oleophobic membrane surface allows these components high resistance to environmental impacts. More >

The uniformly sized pore channels of the TRAKETCH^® ion-track membranes possess a uniformly air flow in comparison to other membranes. At the same time, track-etched membranes are not only hydrophobic, but also oleophobic. Consequently, not only water but also other fluids are being repelled. These properties are important for protecting sensitive equipment which operate under all weather and humidity conditions and need to be protected from particles and remain permeable to air at the same time.

TRAKETCH^® Venting Membranes have unsurpassed pore accuracy for sterile venting. They ensure biocompatibility and are FDA compliant. Our microporous membranes are ultra clean, PFOA/PFCA-free & upon request PFAS-free , non-shedding, with no leachables and extractables. Therefore, they are particularly suitable as single use components which need to protect medical equipment and patients. Examples are spike vents, hearing devices, ostomy bags, transducer protectors and IV sets. More >

Larger-scale buildings using high volume of heated water are at risk of legionella growth. Inhaling these bacteria, for example with the steam when taking a shower, may cause pneumonia. In many countries the concentration of legionellae in the provided heated water in public buildings like hospitals and hotels is supposed not to exceed certain legal limits. We have developed special track-etched membranes for legionella detection.

Microporous membranes prevent particles or bacteria from entering the body. This increases patient safety, reduces hospital stays and contributes to cost efficiency in hospitals. Since there are no fibre shedding PFOA/PFCA-free & upon request PFAS-free track-etched membranes made by SABEU are ideally suited to be used for infusion and drug delivery systems.
