Waterproof 65 Micron Black Color Polyester Screen Mesh with Custom Width and Length

Waterproof 65 Micron Black Color Polyester Screen Mesh with Custom Width and Length

1. Production Process and Standards 

1) Raw Materials and Weaving: High-purity polyester monofilaments are used (to avoid uneven pore size caused by multiple filaments), with plain weave being the mainstream method; Warping → Weaving → Washing and degreasing → High-temperature heat setting (to eliminate internal stress and improve tension stability) → Slitting, inspection, and packaging;

2) Specifications: Mesh count (threads per inch) is the core, commonly 18–420 mesh/inch (7–180 mesh/cm); Supporting parameters include filament diameter (μm), mesh size, mesh thickness, open area ratio, and tension value;

3) Colors: Standard white and yellow (UV resistant, suitable for photosensitive plate making), with custom colors such as black and orange also available; Yellow mesh reduces halo during plate exposure and improves the clarity of fine lines and dots.

2. Core Performance Advantages

1) Low Elongation + High Tensile Stability: Polyester's elastic modulus is much higher than nylon's, resulting in low elongation after stretching. It is less prone to loosening during long-term printing, ensuring extremely high registration accuracy, making it suitable for high-precision printing on PCBs, electronic panels, etc.

2) Chemical and Environmental Resistance: Resistant to weak acids, organic solvents, and water; extremely low hygroscopicity; superior high-temperature resistance compared to nylon; less prone to deformation during outdoor or drying processes.

3) Uniform Mesh Size: Monofilament plain weave + precision setting ensures consistent openings, uniform ink transfer, and sharp edges.

High Cost-Effectiveness: Lower cost than stainless steel mesh, longer lifespan than ordinary nylon mesh, suitable for mass production.
