Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted manufacturer since 1998. Our Polyester Press Mesh (1.5m width, 50m length, 120 mesh, 0.5mm thickness) is engineered for demanding filtration environments. With exceptional acid and alkali resistance, this mesh ensures long service life and consistent performance in chemical processing, wastewater treatment, and food industry applications. Backed by over two decades of manufacturing expertise and annual exports exceeding US$5 million, we deliver reliable quality that meets global standards.
This press mesh is crafted from high-quality polyester fibers, offering excellent dimensional stability and resistance to stretching under pressure. The 120 mesh count provides a fine filtration level, capturing particles down to approximately 125 microns, while the 0.5mm thickness balances strength and permeability. Whether you need a durable filter cloth for plate and frame filter presses or a versatile mesh for liquid-solid separation, our product delivers consistent results.
Key Features & Specifications
- Material: 100% Polyester – high tensile strength, low elongation, and excellent chemical resistance.
- Mesh Count: 120 mesh – precise filtration for fine particles.
- Thickness: 0.5mm – optimal combination of durability and flow rate.
- Width: 1.5m – suitable for standard industrial filter presses.
- Length: 50m per roll – minimizes joints and reduces waste.

Frequently Asked Questions
Q1: What is the exact particle size that this 120 mesh can filter?
A: With a nominal opening of approximately 125 microns, the 120 mesh polyester press mesh can effectively retain particles larger than 125 microns. For finer filtration, we offer higher mesh counts up to 400 mesh.
Q2: Can this mesh be used in continuous high-temperature processes?
A: Yes, it can withstand continuous operating temperatures up to 150°C (302°F). For applications exceeding this limit, we recommend our polyimide or PEEK mesh options.
Q3: Is the mesh resistant to strong acids like sulfuric acid?
A: Polyester has good resistance to dilute acids, but concentrated strong acids (e.g., 98% sulfuric acid) may cause degradation. For highly aggressive chemicals, please consult our technical team for alternative materials.
Q4: How many rolls fit in a 20-foot container?
A: Approximately 200–250 rolls (50m each) depending on packing method. We can optimize packaging to reduce shipping costs.
Q5: Do you offer custom cutting or slit rolls?
A: Absolutely. We can slit the 1.5m width into narrower widths (e.g., 1m, 0.8m) or cut to specific lengths per your requirements. Minimum order quantity may apply.
Q6: What is the typical lead time for bulk orders?
A: Standard production takes 15–20 working days after confirmation. Express delivery (7–10 days) is available for urgent orders with additional charges.
Q7: Do you provide free samples?
A: Yes, we offer free A4-size samples (shipping cost borne by buyer). For larger samples, please contact our sales team.
Q8: Can this mesh be used for reverse osmosis pre-filtration?
A: While it can serve as a pre-filter, the 120 mesh is not fine enough for RO membranes. We recommend a 200–400 mesh for RO pre-treatment.
