Reverse Dutch Weave Mesh (ISO 9044) is specified where the duty calls for high-throughput filtration of polymer melts and viscous fluids with reverse dutch weave, where fine warp and coarse weft wires give a very strong, high-capacity filter belt or pack layer. The sections below cover the typical end-uses by industry, the mesh, micron and material decisions for each, installation practice, and the applications this product type is not suited to.
Typical Applications for Reverse Dutch Weave Mesh
Where Reverse Dutch Weave Mesh is specified and bought:
- Plastic extrusion: continuous screen changer belts and extruder screen packs.
- Synthetic fibers: spin-pack and polymer melt filters.
- Rubber & adhesives: strainer screens for viscous compounds.
- Recycling lines: filters for contaminated regrind melts.
How to Specify Reverse Dutch Weave Mesh for Your Application
- Count: Common: 72 × 15, 132 × 17, 152 × 24, 260 × 40.
- Width & length: Belts for continuous screen changers by width and length.
- Alloy: Plain steel for cost; stainless for corrosive or high-temperature melts.
- Standard: Quote ISO 9044 and the size designation from the table on the product page, plus any value you changed in the technical drawing.
Handling & Installation Practice
- Pre-heat new belts and packs to melt temperature to avoid thermal shock.
- Check belt edges for fraying at every change.
Common Selection Mistakes with Reverse Dutch Weave Mesh
- Using reverse dutch where very fine absolute filtration is needed.
- Wrong orientation of the belt in the changer.
Where Reverse Dutch Weave Mesh Is Not the Right Choice
Not for fine absolute ratings below roughly 50 µm.
