As a leading manufacturer with over 20 years of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Polypropylene Twill Filter Cloth 300 Micron, 600g/m², 170°C, 800N Tensile Strength – a high-performance filtration solution tailored for the pharmaceutical industry. This product combines superior thermal stability, mechanical strength, and precise micron rating to meet the demanding requirements of active pharmaceutical ingredient (API) recovery, solvent filtration, and sterile liquid processing. Our PP twill filter cloth ensures consistent particle retention, excellent cake release, and long service life, helping you optimize production efficiency and reduce downtime.
Manufactured in our ISO-registered facility in Hengshui, Hebei, China, this filter cloth undergoes rigorous quality control at every stage – from raw material selection to final inspection. We utilize advanced twill weaving technology to create a balanced structure that offers both high flow rates and reliable filtration performance. The 300 micron aperture size is ideal for coarse to medium filtration tasks, while the 600 g/m² weight provides exceptional durability even under continuous operation. With a maximum operating temperature of 170°C and tensile strength of 800 N, this cloth withstands harsh chemical environments and mechanical stress, making it a trusted choice for pharmaceutical manufacturers worldwide.
Key Features & Technical Specifications
- Material: 100% virgin polypropylene (PP) – resistant to acids, alkalis, and organic solvents commonly used in pharmaceutical processes.
- Weave Type: Twill weave – provides a smooth surface, good cake release, and reduced blinding compared to plain weave.
- Micron Rating: 300 ± 10% – consistent pore size for reliable particle retention (e.g., removal of crystals, precipitates, or coarse contaminants).
- Weight: 600 g/m² – high density for enhanced mechanical strength and abrasion resistance.
- Temperature Resistance: Continuous operation up to 170°C – suitable for hot filtration processes without degradation.
- Tensile Strength: 800 N (warp and weft) – prevents tearing under high pressure or heavy loads.
- Width: Customizable from 500 mm to 2500 mm – available in rolls or cut pieces to match your filter press, centrifuge, or belt filter.
- Applications: Pharmaceutical API filtration, fine chemical separation, food & beverage, water treatment, and industrial filtration.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lifespan of this filter cloth in pharmaceutical filtration?
A: The lifespan depends on operating conditions such as pressure, temperature, and chemical exposure. Under normal pharmaceutical filtration conditions (e.g., API recovery at 80-120°C), the cloth can last 6-12 months. With proper cleaning and maintenance, it can be reused multiple cycles. -
Q: Can this cloth be used in a filter press for high-pressure applications?
A: Yes, with a tensile strength of 800 N, it is suitable for most filter press applications. However, for extremely high pressure (above 10 bar), we recommend a reinforced version or a heavier weight cloth. Please consult our technical team for specific recommendations. -
Q: Is the material FDA-approved for direct contact with pharmaceuticals?
A: Our polypropylene is manufactured from food-grade virgin resin. We can provide FDA compliance documentation upon request, but it is the customer's responsibility to verify suitability for their specific application and regulatory requirements. -
Q: What are the available widths and lengths?
A: Standard widths range from 1000 mm to 2000 mm. Custom widths up to 2500 mm are available. Rolls are typically 50-100 meters long, but we can cut to specific lengths or provide pre-cut pieces per your order. -
Q: Does the cloth shrink when exposed to solvents or high temperatures?
A: Polypropylene has minimal shrinkage (less than 2%) at temperatures up to 170°C. However, we recommend pre-shrinking the cloth by washing at operating temperature before first use for critical applications. -
Q: How do I clean this filter cloth after use?
A: Common cleaning methods include backwashing with water or solvent, chemical cleaning with mild alkaline solutions, or ultrasonic cleaning. Avoid using strong oxidizers or prolonged exposure to UV light, which can degrade polypropylene. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is 50 square meters. For custom sizes, the MOQ may be higher. We can also offer smaller trial quantities for sample testing. -
Q: Can you provide free samples for evaluation?
A: Yes, we offer free samples (A4 size or small roll) for qualified buyers. The shipping cost may be borne by the customer. Please contact us with your requirements.
