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.

Types

PTFE single-strand knitted mesh

Specifications

• 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.

Features

• 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.

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