We also can finish them with Teflon bathing and membrane. Our polyester needle felt adopt the sound needle punching nonwoven workmanship, with the properties of stable physical dimension, easy cake release, good air permeability, widely used for industrial dust collection and liquid filtration, etc.
After water-oil repelled treatment, which can be used as the filter media in the circumstance contain the moisture and oil mist for a long time.
We also can finish them with PTFE membrane, which will with the properties of smooth surface, easy cake release, high filter efficiency, save energy, long life, etc.

Mainly applications:

  1. Chemicals processing: dryers, bin vents, and nuisance dust collectors in the pigment, plastic, and catalyst industries.
  2. Minerals processing: finish mills, raw mills, bulk pneumatic conveying, and bin-vent dust collectors.
  3. Metals processing: process-venting dust collectors in the lead, lead oxide, and iron and steel industries. Pulverized-coal injection systems, fume and bulk handling systems in coke production and sand-reclamation systems in foundries.
  4. Power generation and Incineration: material handling for coal and limestone
