The product line consists of a carrier medium on which an ePTFE membrane is laminated. The membrane produced from polytetrafluorethylene possesses characteristics which are optimally suited for use in industrial fine dust filtration. Minute pores owing to a micro porous structure, a low surface tension which reduces the adhesion of fine dusts in addition to a temperature resistance of up to 288°C ensure optimum filtration properties.

The advantage with ePTFE membrane

1/ separation of very fine dust particles already on the surface

2/ no penetration of the dust into the substrate

3/ excellent cleaning properties through a smooth, anti-adhesive surface

4/ minimal emission level, zero emission is almost possible

5/ constant differential pressure behavior

6/ constant gas volumetric flow

7/ long service lives and high productivity

     Our company specializes in the manufacture of needle punched felt with membrane laminated for filter bag, including media like as Polyester with PTFE membrane, Nome with PTFE membrane, Homopolymer acrylic with PTFE membrane, PPS with PTFE membrane, 400 gsm Fiberglass with PTFE membrane, 750 gsm Fiberglass with PTFE membrane, Pleated filter cartridge (PP/PTFE/PES/GLASSFIBER filter material) including Polyseter spun bond with PTFE membrane, etc.

  Our needle punched felt  and filter bag are both laminated with e PTFE membrane.  ePTFE membrane is the material of micro porous structure, which the filtering method is the surface filtration. When the trapped dust reaches a certain thickness, it is automatically dropped from the surface of the filter and remained its pressure condition of the starting pressure the filtration efficiency of the coated filter material to the superfine dust can reach 99.99%.

    With above advantages, filter with e PTFE is mainly used in steel mills, cement plants, industrial dust and pharmaceutical industry, precision filter. Through the special hydrophilic treatment, it can also be used in various liquid filters, such as petroleum, chemical industry, smelting of precious metals, minerals to be mined in the sewage treatment, material playback, living sewage processing clean water passivation and so on.
