Description of PTFE Filter Membrane:

As PTFE membrane filter manufacturers, HAWACH Hydrophobic PTFE filter membrane can meet the needs of the most severe gas, and solvent filtration. The pore ​​sizes: 0.1μm, 0.22μm, etc. The membrane is a high-efficiency microporous membrane produced by using polytetrafluoroethylene as raw material.

Advantages of  Hawach PTFE Filter Membrane:

  • HAWACH, which PTFE membrane filter manufacturer, produces hydrophobic and hydrophilic PTFE filter membrane.
  • Microporous PTFE filter membrane refers to a polymer PTFE membrane with a pore size in the range of 0.1 μm to 10 μm, which can trap solid particles and colloidal particles in gas or liquid.
  • It has been widely used in chemical, pharmaceutical, semiconductor, environmental protection, food, beverage, and brewing industries after multi-faceted development.
  • Hydrophobic membrane filter, which is completely made of natural and permanent hydrophobic PTFE material. Even under a very low-pressure difference, it can ensure that the moist air or other gases can pass through without obstruction, while the aqueous solution cannot pass through.
  • Through the control of micropores in the manufacturing process, the best combination of high retention rate and high throughput is achieved.
  • Therefore, HAWACH’s PTFE filter membranes can meet the needs of the most severe gas, solvent filtration, moisture-proof and breathable applications, and improve the process safety of your products.
  • PTFE is suitable for chemically corrosive organic solvents, aqueous solutions, and gases. It is resistant to most acids, alkalis, and solutions. It is a non-hydrophilic membrane, has low protein adsorption, and has good chemical compatibility.
