Polyester fibers are compressed and finishes are applied according to the process or application they are used for. All of the excellent characteristics of polyester apply to polyester felt, including good resistance to chemicals, abrasion and dry heat degradation, plus excellent dimensional stability. Polyester felt is most commonly used in dust collection processes, where the air flow is either forward or reverse pulse. The direction of the air flow dictates the finish required.
Polyester Felt is available in rolls… minimum order: 100 yards

Purpose |
Dust Collection Filter Press |
Acids |
Good resistance to most mineral and organic acids except high concentrations of nitric, sulfuric and carbolic acids. |
Alkalis |
Good resistance to weak alkalis and moderate resistance to strong alkalis at low temperatures. Strong alkalis at high concentrations and temperatures dissolve polyesters. |
Oxidizing Agents |
Good resistance to most oxidizing agents. |
Organic Solvents |
Excellent to most organic solvents, but unsuited for some phenolic compounds and affected by cyclohexanone at 313 ºF. |
