We can provide all the kinds of filter material for air filtration, such as PPS, PTFE, P84, nomex filter bag , acrylic, polyester, fiberglass needle felt or other compounded needle felt as per requirement

1. Feature:

Polyester filter cloth includes Terylene Filament and staple fiber. It has strong acid-resistant ,weak alkali-resistant and it is not dissolved in organic acids. It is very stable in high temperatures for the low concentration of inorganic acid.But it is dissolved in concentrated acid and heating m-cresol. It is easily hydrolyzed in strong alkali.

2 Material property:

acid-resistance, weak alkali-resistance, wear resistance, corrupt-resistance, good reversion performance and good conductivity.

3. Usage:
