0.25mm Thickness Stainless Steel Felt With 70% Porosity

Polymer Melt Filtration

In the production of chemical fibers and films, high-temperature polymer melts require precision filtration to remove gel particles, carbonized residues, and other contaminants. The 10-micron rating of this product effectively protects spinnerets or dies, reducing fiber breakage or surface defects and improving yield rates.

Depth Filtration in Biopharmaceuticals

In cell culture media clarification, fermentation broth polishing, or vaccine manufacturing processes, cell debris, microorganisms, and colloidal particles must be removed. The 0.25mm thin-layer structure allows design as disposable or cleanable filter cartridges, combining high bacterial removal efficiency with low protein adsorption characteristics.

Gas Distribution and Purification in Petrochemicals

Used in gas spargers (e.g., O2 spargers) or pre-filters for gases, high porosity ensures uniform gas dispersion into fine bubbles, enhancing reaction efficiency. Meanwhile, the 10-micron rating effectively captures rust particles, catalyst fines, and other debris from pipelines, protecting downstream sensitive equipment.

Return Oil Filtration in Hydraulic and Lubrication Systems

In hydraulic systems of construction machinery and injection molding machines, return lines require efficient removal of wear particles. The stainless steel felt offers high dirt-holding capacity and cleanability, significantly extending the service life of hydraulic fluids and filter elements while reducing maintenance costs.

High-Temperature Flue Gas and Exhaust Treatment

Suitable for dust removal in industries such as steel, cement, and waste incineration. The stainless steel material withstands temperatures of 200–600°C, allowing direct filtration without cooling, avoiding condensation and acid corrosion issues while meeting ultra-low emission requirements.

Fuel Cell Diffusion Layers and Electrode Supports for Electrolyzers

In the hydrogen energy sector, as a gas diffusion layer or porous electrode substrate, the uniform pore structure facilitates rapid transport of reaction gases and products. The excellent electrical conductivity and corrosion resistance enhance the overall performance and lifespan of fuel cells or electrolyzers.
