Copper-Clad Steel Reverse Dutch Weave Mesh for Polymer Melt Filtration
Why Choose Copper-Clad Steel Reverse Dutch Weave Mesh?
This specialized filter mesh offers distinct advantages over standard stainless steel or plain Dutch weave options:
Advantages | Explanation |
High Tensile Strength | Warp wire tensile strength up to 2,500 N/mm²—significantly stronger than standard stainless steel mesh—helps prevent breakage under high extrusion pressure. |
Corrosion Resistance | Copper cladding provides excellent resistance to corrosion and oxidation, even in high-temperature polymer melt environments. |
Reverse Dutch Weave Design | Delivers higher flow rates than standard Dutch weave while maintaining excellent particle retention—ideal for continuous, high-volume filtration. |
Heat Resistance | Withstands the high temperatures encountered in plastic and rubber extrusion processes without losing structural integrity. |
Anti-Clogging Performance | The reverse Dutch weave pattern resists blinding and plugging, reducing cleaning downtime and helping extend filter life. |
Precise Filtration | Uniform mesh openings ensure consistent particle retention, improving product quality (e.g., film clarity and fiber consistency). |
Long Service Life | Durable construction resists abrasion and repeated thermal cycling, reducing replacement frequency and operating costs. |
Compatibility | Designed for use with all automatic screen changer systems—compatible with both imported (Austrian, German, Japanese) and domestic Chinese extrusion equipment. |

Reverse Dutch Weave: The Optimal Pattern for Melt Filtration
Reverse Dutch weave is a specialized weave pattern that reverses the configuration of standard Dutch weave:
Weave Type | Warp (Meridian/Vertical) | Weft (Latitude/Horizontal) | Characteristics |
Standard Dutch Weave | Thicker | Thinner | Dense surface; maximum particle retention |
Reverse Dutch Weave | Finer, denser | Thicker, stronger | Higher flow rates; better anti-clogging |
Key features of reverse Dutch weave for melt filtration:
Feature | Explanation |
Dense Warp Packing | Finer warp wires are packed closely together, forming a dense filter surface that captures fine particles. |
Strong Weft Support | Thicker weft wires provide structural reinforcement, preventing belt deformation under high extrusion pressure. |
Triangular Openings | The warp–weft interaction creates triangular-shaped transverse openings that promote flow and resist clogging. |
Anti-Slip & Anti-Shifting | The tightly woven structure helps prevent belt misalignment and wire shifting during continuous operation. |
Verdict: This combination of materials and weave makes copper-clad steel reverse Dutch weave mesh an industry-standard solution for polymer melt filtration, rubber processing, and automatic screen changer applications.

Copper-Clad Steel vs. Stainless Steel Reverse Dutch Weave
Feature | Copper-Clad Steel Reverse Dutch Weave | Stainless Steel Reverse Dutch Weave |
Tensile Strength | Higher (up to 2,500 N/mm²) | Standard (approx. 600 – 800 N/mm²) |
Corrosion Resistance | Good (copper cladding protects the steel core) | Excellent (especially 316 grade) |
Conductivity | Excellent (copper is highly conductive) | Low |
Heat Resistance | High (copper maintains integrity at melt temperatures) | Very high |
Cost | Moderate (copper cladding adds value) | Lower to moderate (depends on grade) |
Primary Use | Polymer melt filtration (high pressure, continuous operation) | General industrial filtration |
Screen Changer Compatibility | Excellent (industry standard for melt filtration) | Good |
Verdict: For polymer melt filtration and automatic screen changer applications, copper-clad steel delivers superior tensile strength and is an industry-standard choice. For general chemical or pharmaceutical filtration, stainless steel may be sufficient and more cost-effective.
