Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, proudly presents our Calendered Surface PET Filter Cloth for Belt Filter. With a thickness of 0.2mm and a smooth finish, this filter cloth is engineered to deliver superior filtration performance in belt filter applications. Our advanced calendering process ensures a uniform, non-stick surface that enhances cake discharge and reduces blinding, making it an ideal choice for dewatering, solid-liquid separation, and chemical processing. Backed by decades of expertise and annual export value exceeding US$5 million, we offer reliable solutions for global markets including North America, Europe, and Asia.
This product is made from high-quality Polyester (PET) fibers, providing excellent chemical resistance, dimensional stability, and long service life. The calendered surface not only improves filtration efficiency but also minimizes particle entrapment, leading to consistent performance. Whether you need custom widths or specific weave patterns, our flexible manufacturing capabilities allow for tailored solutions to meet your unique requirements.

Frequently Asked Questions
Q1: What is the advantage of a calendered surface compared to a standard finish?
A: The calendered surface undergoes a heat and pressure treatment that creates a smooth, non-porous layer. This reduces particle adhesion, improves cake release, and extends the cleaning interval. It also enhances the fabric's dimensional stability and reduces the risk of blinding.
Q2: Can this filter cloth be used for acidic or alkaline solutions?
A: Yes, PET (polyester) has good resistance to most acids and alkalis at moderate concentrations. However, for highly aggressive chemicals, we recommend confirming compatibility with our technical team. We can also suggest alternative materials if needed.
Q3: What is the maximum width available for this product?
A: Our standard maximum width is 2.5 meters, but we can produce custom widths up to 3.5 meters upon request. Please provide your specific requirements for a quotation.
Q4: How does the 0.2mm thickness affect filtration performance?
A: The 0.2mm thickness provides a balance between high flow rate and effective particle retention. It is ideal for applications where a thin filter medium is required to achieve low pressure drop and efficient cake formation.
Q5: What is the typical lead time for bulk orders?
A: For standard specifications, lead time is 15-20 working days after order confirmation. Custom orders may require additional time, depending on complexity. We expedite urgent requests when possible.
Q6: Do you provide samples for testing?
A: Yes, we offer free samples of A4 size or small rolls. Customers only need to pay for shipping. Please contact us with your application details so we can recommend the most suitable variant.
Q7: Is this filter cloth suitable for food-grade applications?
A: Our PET filter cloth is manufactured from raw materials that are generally recognized as safe for food contact. However, compliance with specific food safety regulations (e.g., FDA, EU) should be verified on a case-by-case basis. We can provide material certificates upon request.
Q8: What is the difference between calendered and non-calendered PET filter cloth in terms of cake moisture?
A: The calendered surface typically produces a drier cake because the smooth texture reduces moisture retention and allows for better dewatering. Many users report 1-3% lower cake moisture content compared to non-calendered fabrics.
