Hydrophobic PTFE Membrane Discs With Optional PP/PET Supportive Backing

PTFE filters, also known as polytetrafluoroethylene (PTFE) filters, are a type of filter membrane that exhibit chemical and biological inertness. This means that they are not affected by or react with chemicals or biological substances. They are stable up to 260°C, which is a high temperature that is well within the range of normal operating temperatures for many applications. PTFE membrane disc filters we offer are hydrophobic and laminated with optional PP or PET supportive backing. They are very useful for air venting, gas filtration and removal of aerosol comtaminants. These membranes are manufactured through a patented process to form a high-porosity, uniformly thick and thermostable structure. PTFE with PP or PET supportive backing possesses the qualities of standard PTFE membranes, but have the additional benefit of a backing layer making them thicker and easier to handle.

PTFE membrane disc units are naturally hydrophobic, this feature makes them suitable for no-aqueous filtration applications. The hydrophobic nature of the material ensures that water and other liquids do not penetrate or stick to the surface, allowing for efficient filtration without the need for aqueous media.

PTFE disc membrane filters have broad chemical compatibility, exhibiting exceptional resistance to strong acids and aggressive solvents. Their chemical resilience allows them to withstand a wide range of chemicals and substances in a wide range of applications where chemical and biological resistance is important. For example, PTFE filters can be used in medical devices, such as catheters and tubing, where exposure to chemicals and biological fluids is common. They can also be used in industrial processes, such as chemical processing and food manufacturing, where stability and resistance to contamination are critical.

PTFE membrane discs with PP or PET supportive backing has superior dimensional strength. They can withstand aggressive handling and forceful operations, making them ideal for use in demanding industrial applications where high-strength materials are required. Additionally, their excellent dimensional strength contributes to their durability and longevity, ensuring they can withstand repeated usage without breaking down prematurely.

Applications

Hydrophobic PTFE membrane disc filters are chemically resistant to virtually all solvents. They can be used for working with aggressive media such as strong acids, alcohols, bases, aromatics. The PTFE membrane disc units are ready-to-use and allow for simple, rapid and reliable ultra-cleaning of small volume samples for HPLC or GC analysis. PTFE disc filters can also be used to prevent moisture passing through air vents. Hydrophobic PTFE membranes can also be used for filtering aqueous solutions, if pre-wetted with alcohol.
