PTFE (Teflon) Filter Bags


Dewdon’s PTFE filter bag is made by a three-dimensional and has a very strong high temperature resistance, wear resistance, corrosion resistance, chemical stability and good hydrolyzed resistance. It is easy to clean dust with its smooth surface, continuous working temperature 240°C, peak 260°C.

These filter bags are manufactured by the lamination of a PTFE membrane to the fabric which makes the filter resulting in PTFE Membrane Filer Bags. These Membrane Filter Bags are of vital importance in industries where powder recollection is a necessity and hence finds a prominent place in the chemical and dye industry along with cement and carbon works. The PTFE membrane, when it is laminated drastically increases the filtration efficiency of the filters to up to 99.99% and results in a complete dust cake formation after the utilization.

For aqueous solutions, PTFE must be pre-wetted with a solvent such as isopropyl alcohol or ethanol.
