PTFE Knitted Mesh with Excellent Resistant to Strong Acids and Bases

PTFE knitted mesh is widely used in gas-liquid filtration applications. Working as a filter mesh, PTFE knitted mesh has excellent resistant to chemicals and high temperatures due to its inherent properties and can be used in any kind of chemical media for a long period. However, it has a smooth surface and is not easy to be compressed, therefore, it commonly works with stainless steel woven mesh to enhance its support performance.

Many white PTFE knitted mesh rolls are displayed.

  • Wire diameter: 0.1 mm – 0.55 mm
  • Mesh width: 40 mm, 80 mm, 100 mm, 150 mm, 200 mm, 300 mm, 400 mm, 500 mm, 600 mm
  • In addition, other specifications are available upon request.


  • Chemical stability. It has great resistant to strong acids, strong bases (hydrofluoric acid, phosphoric acid, sulfuric acid, nitric acid, hydrochloric acid and various organic acids) and a variety of organic solvents, and can withstand extreme chemical conditions.
  • Thermal stability
    • High temperature resistance, 400 °C maximum decomposition temperature and up to +250 °C working temperature;
    • Low temperature resistance, it can maintain 5% elongation and good mechanical strength even at -196 °C
  • Self-Lubricating. Among solid materials, it has a low coefficient of fraction (0.04) and is not easy to attach to any substance.
  • Insulating property. Its dielectric property is unrelated to temperature and frequency.
  • Nontoxicity. It is chemically inert. Its lead content is less than 10–11 g/ml of lead and uranium content is less than 10–12 g/ml.
  • Lightweight. PTFE knitted mesh is lighter than metal knitted mesh, easy to install and replace.

PTFE knitted mesh is widely used in gas-liquid filtration applications, such as industrial flue gas desulfurization mist eliminator, demister pad.

A round PTFE mist eliminator is displayed.
