Product Introduction:<\/strong>PTFE needle punched felt is a filtering material made of PTFE (polytetrafluoroethylene fiber) through three-dimensional needle punching.. PTFE fibers have a linear structure of large molecules, making PTFE needle punched felt highly resistant to temperature, wear, corrosion, and chemical stability. It is widely used in various harsh flue gas filtration environments such as steel, electricity, and waste incineration.

Product performance:<\/strong>Made of 100% pure PTFE;; Applicable temperature -210 \u2103 to 265 \u2103; Acid and alkali resistance, corrosion resistance, and extremely strong chemical stability (0-14PH); The same applies to high humidity environments; Not easily aged; pollution-free; Fabric composition: PTFE short fibers (PTFE curled fibers can be blended with other fibers to reduce costs and maintain a certain degree of non adhesiveness). The appearance is pure white. The content is 100% polytetrafluoroethylene (PTFE). When processing, if the needle count is greater than 62 per square centimeter, anti-static agents should be used, all steel equipment should be used, and grounding devices must be used. \uff09+100% PTFE base fabric (woven from 500dtex filament fibers (monofilaments), with a plain weave structure. PTFE base fabric can be designed with different warp and weft densities according to the strength requirements of the filter material. For example, with 140 fibers per 10cm in the warp direction and 140 fibers per 10cm in the weft direction (140\/\u33a1), the warp and weft strength of the base fabric can both exceed 1000N. Based on the chemical stability of polytetrafluoroethylene raw materials, it is the most chemically resistant and stable product among all filter materials.<\/p>\n

1\u3001 The continuous working temperature is above 250 degrees Celsius, and the instantaneous temperature is 280 degrees Celsius.<\/p>\n

2\u3001 Completely unafraid of acidity, alkalinity, and oxidation, almost non flammable.<\/p>\n

3\u3001 The only fiber that does not age.<\/p>\n

4\u3001 Satisfy the worst working conditions and have an extremely long service life, typically exceeding 4 years.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
