Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of experience since 1998. Our Polypropylene Filter Cloth for Belt Filter with 120μm Aperture and 2mm Thickness is engineered to deliver reliable and efficient solid-liquid separation in demanding industrial processes. Made from high-quality polypropylene monofilament, this filter cloth offers excellent chemical resistance, dimensional stability, and consistent filtration performance. Whether you are dewatering sludge, processing minerals, or filtering chemicals, our product ensures long service life and minimal downtime.
The 120-micron aperture is precisely controlled to capture fine solids while maintaining high flow rates, and the 2mm thickness provides robust mechanical strength and abrasion resistance. This filter cloth is specifically designed for belt filter presses, belt thickeners, and similar equipment, offering a perfect balance between filtration efficiency and cake release.
Key Features and Technical Specifications
- Material: 100% virgin polypropylene (PP) monofilament – excellent acid/alkali resistance, non-toxic, and recyclable.
- Aperture: 120 μm (±5%) – uniform mesh opening for consistent filtration.
- Thickness: 2.0 mm (±0.1 mm) – optimal for pressure and wear resistance.
- Weave Type: Available in plain weave, twill weave, or double-layer weave – customizable to your application.
- Air Permeability: Moderate to high – ensures quick drainage and reduced cycle time.
- Tensile Strength: Warp ≥ 800 N/cm, Weft ≥ 600 N/cm (typical values).
- Operating Temperature: Continuous up to 90°C (short-term up to 110°C).
- Width: Up to 3.5 meters in one piece, and can be cut to any length.
- Color: Standard white, but other colors available upon request for easy identification.
- Edge Treatment: Heat-cut, hemmed, or reinforced with PVC or PU tape – prevents fraying and extends life.
Typical Applications
- Municipal and industrial sludge dewatering in belt filter presses.
- Mining and mineral processing (coal, iron ore, copper, etc.).
- Chemical and pharmaceutical filtration.
- Food and beverage processing (e.g., starch, sugar, juice).
- Paper and pulp industry.
- Environmental protection and wastewater treatment.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum temperature this filter cloth can withstand?
A: The polypropylene filter cloth can be used continuously at temperatures up to 90°C (194°F). Short-term exposure up to 110°C is possible, but prolonged high temperature may reduce lifespan. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer free samples (size A4 or 1m²) for testing. You only need to pay for shipping. Please contact us to arrange. -
Q: What is the recommended storage condition for this filter cloth?
A: Store in a cool, dry place away from direct sunlight and UV sources. Avoid contact with sharp objects. The product has a shelf life of at least 3 years if stored properly. -
Q: How do I install the cloth on my belt filter?
A: We provide installation instructions and can also offer technical support via video call. The cloth is typically cut to size and installed with mechanical fasteners or adhesive. Our edge finishing options (hemmed, taped) make installation easier. -
Q: Is this filter cloth suitable for acidic or alkaline conditions?
A: Yes, polypropylene has excellent resistance to most acids (e.g., sulfuric, hydrochloric) and alkalis (e.g., sodium hydroxide) at moderate concentrations. For extreme pH or high-temperature chemical environments, please consult our technical team for recommendations. -
Q: Can you provide a custom weave pattern or different aperture sizes?
A: Absolutely. We can produce filter cloth with apertures ranging from 10 μm to 2000 μm, and various weave patterns (plain, twill, satin, double-layer). Custom thicknesses from 0.5 mm to 4 mm are also available. Minimum order quantity may apply for custom specifications. -
Q: What is the typical lead time for standard orders?
A: For standard specifications (120μm, 2mm, white, plain weave), we can ship within 7-10 working days after confirmation. For customized orders, lead time is 15-20 working days. -
Q: How do you pack the filter cloth for export?
A: We use strong woven polypropylene bags or cardboard boxes with moisture-proof lining. Each roll is labeled with product details, and we can also provide neutral packaging if required.
