The Unique good chemical resistance is a major benefit of ePTFE-membranes. These are incredibly chemically resistant membranes, and that’s good for applications so you’re not wrecking equipment when you have harsh chemicals coming down the line of a process. In addition, ePTFE membranes are also very resistant to heat and UV-light, therefore suitable for outdoor applications in which exposure to the elements is required.
The excellent service life of ePTFE membranes is another important benefit. These are very strong films with good tensile strength, suitable for applications where mechanical properties are critical. Furthermore, ePTFE membranes are tear and puncture resistant making them durable for industrial applications
.
Besides dealing with a specialist like Unique also look at industrial material distributors that carry ePTFE membranes. Such distributors typically have relationships with several manufacturers, and thus have a long list of options to provide. It is important to work with a distributor that can offer various ePTFE membrane product options and help you determine the best alternative for your specific application.
ePTFE membranes resist most chemicals, so they perform well in rugged conditions that wear out other materials. They are also very reliable as it can tolerate heat and cold and remain in its place for long time. Moreover, ePTFE membranes are also breathable to the passage of gases so that they allow air molecules to pass through while preventing liquids and impurities from coming through. This trait makes them advantageous in applications involving filtration and venting.
Pore size, thickness and surface modification of the ePTFE membrane should be taken into account when selecting a membrane for your application. The filtration efficiency of the membrane is dependent on the pore size, where greater filter may reduce airflow or vice versa. The membrane thickness will affect durability and puncture resistance. Surface character (hydrophobicity or oleophobicity) can affect interaction of the membrane with liquids and contaminants. By paying attention to these points, you can choose the ePTFE membrane that is right for you.
