The chemical fiber melt filter element mainly uses stainless steel woven mesh or stainless steel fiber sintered felt as the filter medium. Stainless steel woven mesh, woven from fine metal wires, provides smooth channels, easy cleaning, high temperature resistance, corrosion resistance, no wire shedding, and long service life; stainless steel fiber sintered felt is a porous deep filtration material made through high-temperature sintering of fibers, with high porosity, strong contaminant holding capacity, good permeability, and reusability. This filter features uniform pore size distribution, stable filtration performance, and low flow resistance, while being strong, durable, and resistant to high-pressure impact. It can operate under high temperature (≤600 °C) and high differential pressure reliably. With a stable structure that resists detachment even in harsh environments, it is widely used for high-temperature melt, gas, and liquid precision filtration, particularly in synthetic fiber, pharmaceutical, electronics, and chemical industries.
