A Feeling Like No Other
Polyester Felt (PE) reigns as the most widely utilized and cost-effective filter felt in modern pulse jet baghouses. This adaptable felt serves a broad spectrum of applications, ranging from cement manufacturing to electric furnace operations and beyond. With a maximum continuous operating temperature reaching 275°F, polyester felt stands up favorably against homopolymer acrylic felt and outperforms Nylon (Cerex®), polypropylene, and cotton-woven filter media. Given its array of benefits, it’s clear why polyester felt is a favored option for filter bag applications!
Reliable and Robust Synthetic Option
Thanks to its excellent dimensional stability, polyester felt holds its ground as the predominant type of filter bag on the market today. It excels in dry heat applications, outperforming many other synthetic materials, with the exception of Nomex® (Aramid) and Teflon®. However, polyester felt is generally not recommended for applications involving moist heat, as it can experience hydrolytic degradation in specific conditions. Regardless of this limitation, polyester felt is offered in multiple finishes, enhancing its performance for various requirements and applications.

Unmatched Chemical Resistance
Polyester filters have built a solid reputation for their remarkable resistance to chemical exposure, abrasion, and degradation due to dry heat. This impressive capability includes resistance to a majority of mineral and organic acids, barring high concentrations of nitric, sulfuric, and carbolic acids. Furthermore, polyester felt possesses good resistance to weak alkalis and moderate resistance to strong alkalis at low temperatures. It also shows commendable resistance to most oxidizing agents and outstanding resistance to many organic solvents. Although polyester felt handles a range of chemicals adeptly, it’s advisable to avoid certain phenolic compounds. But, as the saying goes, nobody is perfect!
