As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory (established in 1998) proudly presents our Polypropylene Twill Filter Cloth with a 20-50 micron filter rating, 180°C melt point, and 800g/m² weight. This high-performance filter media is engineered to deliver exceptional durability and precise filtration across a wide range of industrial applications. Our factory, located in Hengshui, Hebei, China, exports annually between US$5 million and US$10 million to markets worldwide, including North America, Europe, Southeast Asia, and the Middle East, ensuring consistent quality and reliable supply.
This filter cloth combines the strength of polypropylene with the versatility of a twill weave, making it ideal for demanding filtration tasks where chemical resistance and thermal stability are required. Whether you need to separate solids from liquids, capture fine dust particles, or dewater slurries, our product offers a long service life and low maintenance. Read on to discover the detailed features, technical specifications, and benefits that set this filter cloth apart.
Key Features & Advantages
- Excellent Chemical Resistance: Polypropylene is resistant to most acids, alkalis, and organic solvents, ensuring long-term performance in harsh environments.
- High Temperature Stability: With a melting point of 180°C, this cloth can withstand continuous operating temperatures up to 90-100°C, making it suitable for hot filtration processes.
- Precise Filtration Rating: The 20-50 micron range provides efficient particle retention for medium to fine filtration applications.
- Heavy-Duty Construction: The 800g/m² weight and twill weave offer excellent tensile strength, tear resistance, and dimensional stability, even under high pressure.
- Low Moisture Absorption: Polypropylene absorbs less than 0.1% moisture, preventing swelling and maintaining consistent filtration performance.
- Easy Cake Release and Cleaning: The smooth surface of the twill weave facilitates easy discharge of filter cake and simple washability, reducing downtime.
- Customizable Dimensions: Available in various widths, lengths, and edge finishes (sewn, welded, or grommeted) to fit your specific equipment.

Frequently Asked Questions (FAQ)
Q1: What is the difference between twill and plain weave filter cloth?
A: Twill weave has a diagonal pattern that offers higher strength, better cake release, and less particle blinding compared to plain weave. It is ideal for heavy-duty applications where mechanical stress is high.
Q2: Can this filter cloth be used for acidic or alkaline solutions?
A: Yes, polypropylene is highly resistant to most acids, alkalis, and many organic solvents, making it suitable for harsh chemical environments.
Q3: What is the maximum operating temperature?
A: Continuous operation is recommended up to 90°C (194°F), with short-term peaks up to 110°C (230°F). The 180°C melting point provides a safety margin.
Q4: How do I choose the correct filter rating for my application?
A: The 20-50 micron range is suitable for medium to fine filtration. If you need finer or coarser filtration, we can customize the weave and weight. Contact our technical team for a recommendation.
Q5: Is this cloth suitable for filter presses?
A: Absolutely. The 800g/m² weight and twill construction provide excellent strength and dimensional stability, making it a popular choice for both plate and frame and recessed chamber filter presses.
Q6: Can I get custom sizes or cut pieces?
A: Yes, we offer custom widths, lengths, and cut pieces with various edge finishes (sewn, welded, hemmed). Please provide your equipment dimensions for a tailored solution.
Q7: What is the typical lead time?
A: For standard sizes, lead time is 7-15 days after order confirmation. Custom orders may require 15-25 days, depending on volume and complexity.
Q8: Do you provide samples before bulk order?
A: Yes, we can provide samples (A4 size or small swatches) for evaluation. Shipping cost may apply, but we will deduct from the first order.
