Never Felt Like This Before
Polyester Felt (PE) is the most commonly used and most cost effective filter felt used in modern pulse jet style baghouses. This versatile felt has an extensive variety of uses and applications ranging from cement plants to electric furnaces and everything in between. With a normal maximum continuous operating temperature of 275°F, polyester felt is comparable to homopolymer acrylic felt, and surpasses Nylon (Cerex®), propylene, and cotton woven filter media. With so many benefits, it makes sense that polyester felt is such a popular choice for filter bag applications!  

The Stable, Superior, Synthetic
Featuring excellent dimensional stability, it&#;s no surprise that polyester felt is the most common type of filter bag used today. Polyester is especially good for dry heat applications and is far superior to other synthetics with the exception of Nomex® (Aramid) and Teflon® in this regard. Conversely, a polyester felt filter isn&#;t generally a good choice for moist heat since it&#;s subject to hydrolytic degradation under certain sets of circumstances. Despite this slight drawback, polyester felt is available in numerous finishes which improve its performance for different requirements and applications.

Irresistible Resistance
Polyester filters have earned a great reputation for their superior resistance to chemicals, abrasion, and dry heat degradation. This impressive resistance extends to most mineral and organic acids with the exception of high concentrations of nitric, sulfuric, and carbolic acids. Additionally, polyester felt has good resistance to weak alkalis, and moderate resistance to strong alkalis at a low temperature. Polyester also has good resistance to most oxidizing agents and excellent resistance to most organic solvents. Despite having impressive resistance to so many chemicals, It is not recommended for some phenolic compounds. Oh well, nobody&#;s perfect!
