Waterproof Polyester Needle Punched Felts

In order to improve the adaptability of polyester needle felt to some application conditions or to improve its filtration precision, some finishing treatment was carried out to derive some new types.

According to the desired effect after treatment, there are:Oil proof and waterproofing treatment, which mainly solves the problem of water condensation in the system.

How to test the water proof effect:

Drop a drop of water to the polyester needle punched felt 

Then flow it , if the water enter into the polyester needle punched felt , polyester needle punched felt hasn't any water proof treatment . 

If the water become many small drops on the polyester needle punched felt and free slip through the surface of polyester needle felt , means that this kind of polyester needle punched felt has water proof treatment.

Advantage

●Excellent waterproof performance

● Resist strong acid and weak alkali

Specification

Why Us

1.High filtration efficiency

PTFE membrane filter material, , smooth surface, high dust peeling strength, easy ash removal, filtration efficiency up to 99.99%, greatly exceeding the national standard.

2.Wide adaptability of the environment:

PTFE membrane filter material has strong temperature resistance, wear resistance, chemical resistance, temperature, humidity and corrosive temperature, humidity and corrosive gases, especially has better effect on high concentration, high humidity and fine particles containing dust. These are ordinary filter media can not be compared.

3.Good air permeability

The air permeability of PTFE membrane filter material can reach 2-5 m3/m2.min, which exceeds the requirement of actual use.

4.Economic benefits

PTFE membrane filter material has the strong chemical and physical properties, the service life of the product can be up to 3-4 years under normal working conditions, and more valuable powder can be recovered dust, economic benefits can be imagined.
