Product features:
Excellent chemical stability, smooth surface, high temperature resistance,low aging, long service life, with good air permeability and dewing resistance. Especially suitable for application which has high concentration and high humidity dust, high adhesion dust or high purification requirement environment.
Application:
Our PTFE membrance filter media is made with PTFE micron hole membrance and needle felt, widely used for air filtration,flue gas cleaning and dust removal, dust pollution control.
The PTFE membrance can be applied on both normal temperature and high temperature needle felt.
