Green PTFE Coated Wire Mesh With Fantastic Hydrophobic Performance

1. PTFE Coated Wire Mesh Description

PTFE coating provides additional strength to the mesh as well as protecting the mesh from contaminants during use. PTFE coated products enhance the performance of filtration systems, particularly for industrial cartridge filters.

PTFE coating can be done perfectly to fully coat the strands of the woven mesh without filling in the apertures. Most woven mesh used for this method of filtration is either 100 200 325 mesh size, manufactured from stainless steel wire threads.

When surface materials are coated with PTFE, water droplets rest on the surface, without actually wetting to any significant extent. PTFE coatings are used to increase the hydrophobic performance of the filter, by means of permitting fuels to pass through but inhibit the passage of water in coalescer based systems. In such systems the PTFE coated mesh can be easily cleaned during maintenance and service operations. It has been found that PTFE coated mesh filters can help to reduce operating costs and improve product quality.

Our PTFE coated mesh has a plain weave and meets the ANSI/AWCI-01 standard specification for wire fabric, ASTM E 2016-99 for industrial woven wire cloth, and RR-W-360 for industrial wire fabric. 100 and 200 weaves can be cut with heavy-duty scissors, and we can also precision-cut PTFE discs, rectangles, and other shapes as needed.

3. PTFE Coated Wire Mesh Features

PTFE is a dark green non-stick coating usually applied to stainless mesh products in a layer approximately one millimeter thick. The green color of the PTFE coating is traditional for this type of coated mesh. It will vary among mesh rolls and possibly within a single roll, but color variation does not have any impact on the performance or effectiveness of the mesh.

It holds up under temperatures of up to 500 °F, which is higher than any other fluoropolymer coating. Even with very fine mesh weaves, PTFE will not “bridge” any of the openings between the wires. The finished mesh product is also easy to clean and will not maintain chemical pollutants or other residues on the surface after they pass through.

4. PTFE Coated Wire Mesh Application

PTFE is a food-grade coating, but this type of wire mesh can be used in a wide variety of industries for several different applications including coalescing filtration. PTFE is a hydrophobic coating, meaning when water passes through PTFE wire mesh, it will bead onto the surface, allowing other substances to pass through. It is effective in separating water from various kinds of fuel and is often used in the manufacturing industry to filter liquids and gases.

PTFE coated mesh also has a wide range of industrial and scientific uses such as paper fabrication and petroleum purification. In addition to filtration and purification, this type of mesh is often used to separate and dry small particles. Because PTFE coated mesh allows for air to pass through while repelling moisture, it is sometimes used for water-resistant speakers, microphones, and other devices with similar requirements.

PTFE coated wire mesh are commonly used as filter element in industrial applications.

♦ Chemicals, resins and solvents.

♦ Hydraulic oils.

♦ Petroleum refining.

♦ Power generation.

♦ Pulp and paper industry.

♦ Fuel lines.
