This high-performance industrial filter material is widely used in wastewater treatment, chemical processing, textile dyeing, steelmaking, papermaking, and other industries. It is engineered for superior strength, acid and alkali resistance, wear resistance, permeability to air and water (while remaining impermeable to sludge), and effective solid-liquid separation. Its design facilitates easy sludge release after pressing, simplifying cleaning and maintenance.

Material

• Main Component: Polyester fiber, typically polyethylene terephthalate (PET)
• Auxiliary Materials: Additives (anti-aging, anti-oxidation) and coatings (polyurethane) to enhance wear and corrosion resistance.
