涤纶覆膜针刺毡 Polyester coated needle felt
Polytetrafluoroethylene (PTFE) film surface smooth and resistant to chemical substances, will be covered into the surface of the polyester needle felt, played a role in the disposable dust layer, all the dust trapped in the surface of the membrane, to achieve surface filtration; Because the film surface is smooth, with excellent chemical stability, no aging, and hydrophobic, so that the dust trapped on the surface is easy to peel off, while improving the service life of the filter.
