PTFE-coated stainless steel filter mesh is a functional filtration material based on woven stainless steel wire mesh (such as SUS304, 316L, or 321) that has been uniformly coated with polytetrafluoroethylene (PTFE) fluororesin and cured via high-temperature sintering. This product combines the mechanical strength and dimensional stability of stainless steel mesh with the corrosion resistance, non-stick properties, hydrophobicity, and ease-of-cleaning characteristics of a PTFE coating. It is well-suited for filtration, screening, and separation processes involving corrosive media, viscous materials, or specialized industrial environments.
Description
Product Features
- Corrosion Resistance
PTFE coating provides excellent resistance to acids, alkalis, and various chemical media.
- Anti-Stick and Anti-Clogging Properties
Low surface friction reduces the adhesion of oils, slurries, and sticky materials.
- Easy Cleaning
The smooth surface resists dirt buildup and facilitates washing, backwashing, and maintenance.
- Temperature Resistance
Typical long-term operating temperature ranges from -40°C to 260°C.
- Mechanical Strength
Stainless steel substrates provide good tensile strength and structural stability.
