Welcome to Anping County Boli Hardware Wiremesh Products Factory. As a dedicated manufacturer with over 25 years of industry experience since 1998, we are proud to present our Acid & Alkali Resistant Polyester Spiral Mesh — a high-performance filtration solution engineered for demanding industrial environments. This premium mesh features a thickness of 2mm and an open area of 50%, offering an optimal balance of strength and flow efficiency. Its exceptional resistance to acids, alkalis, and temperatures up to 300°C makes it ideal for harsh chemical processing, mining, and wastewater treatment applications. With annual export values reaching US$5-10 million and a global customer base spanning North America, Europe, Asia, and Oceania, our mesh is trusted by industries worldwide for reliability and durability.
Our polyester spiral mesh is manufactured using advanced weaving techniques that ensure uniform structure and consistent performance. The spiral design provides excellent flexibility while maintaining high tensile strength, reducing the risk of deformation under heavy loads. The 2mm thickness offers robust physical stability, and the 50% open area promotes efficient liquid or gas passage with minimal pressure drop. This combination is particularly suited for applications requiring both mechanical strength and chemical resistance.
Key Features & Technical Specifications:
- Exceptional Chemical Resistance: Withstands strong acids (e.g., sulfuric, hydrochloric) and alkalis (e.g., sodium hydroxide) without degradation. Ideal for aggressive chemical filtration.
- High Thermal Stability: Operates continuously at temperatures up to 300°C, suitable for hot gas filtration, drying processes, and high-temperature liquid separation.
- Optimal Open Area (50%): Balances high flow rates with effective particle retention. Reduces clogging and extends service life.
- Durable 2mm Thickness: Provides robust mechanical strength, resisting tearing and abrasion under repeated use.
- Spiral Weave Design: Offers flexibility for easy installation and conformability to curved surfaces, while maintaining structural integrity.
- Customizable Dimensions: Available in various widths, lengths, and roll sizes to meet specific equipment requirements.
- Low Maintenance: Smooth surface and anti-stick properties reduce cleaning frequency and downtime.

Frequently Asked Questions
Q1: Can this polyester spiral mesh be used in continuous contact with concentrated sulfuric acid?
A1: Yes, our polyester mesh exhibits excellent resistance to concentrated sulfuric acid at room temperature. However, for elevated temperatures or prolonged exposure, we recommend testing under your specific conditions. Please contact our technical team for detailed compatibility data.
Q2: What is the maximum roll length available?
A2: Standard rolls are 30 meters or 50 meters in length, but we can customize any length up to 100 meters per roll. Widths can also be tailored to your equipment.
Q3: Is the 300°C heat resistance continuous or intermittent?
A3: The 300°C rating is for continuous operation. Short-term exposure to slightly higher temperatures (e.g., 320°C) is possible but may affect lifespan. For peak temperatures above 300°C, please consult us for alternative materials.
Q4: How does the 50% open area compare to standard woven meshes?
A4: The 50% open area is relatively high, providing good flow while maintaining strength. This design reduces pressure drop and improves filtration efficiency for slurries and viscous liquids.
Q5: Can this mesh be used for food-grade applications?
A5: Our polyester material is generally considered food-safe (FDA compliant upon request). However, we recommend verifying compliance with local food contact regulations. We can provide material certificates for specific batches.
Q6: What is the typical lead time for orders?
A6: For standard sizes and quantities, lead time is 15-20 working days. Custom orders may require 25-30 working days. We offer expedited shipping for urgent requirements.
Q7: Do you offer samples for testing?
A7: Yes, we provide free samples of A4 size (20x30 cm) for evaluation. The customer pays only shipping cost. Contact us with your requirements.
Q8: How is the mesh packaged for export?
A8: Each roll is wrapped in protective plastic or kraft paper, then packed in woven bags or wooden crates for sea freight. We ensure moisture protection and secure handling to prevent damage during transit.
