As a professional manufacturer with over 20 years of experience, Anping County Boli Hardware Wiremesh Products Factory (est. 1998) presents our Sintered Phenolic Resin Filter Element for Chemical Processing Liquid Filtration, designed to withstand pressures up to 10 Bar. This filter element is engineered to provide reliable and efficient solid-liquid separation in aggressive chemical environments, leveraging our advanced sintering technology to create a robust, porous structure that resists corrosion and maintains consistent performance. With annual exports between US$5-10 million and serving markets across North America, Europe, Southeast Asia, and beyond, our products meet the rigorous demands of global industrial clients.
The sintered phenolic resin filter element is a high-performance solution for removing particulates from chemical liquids, including acids, alkalis, solvents, and other corrosive media. Its unique manufacturing process bonds phenolic resin particles under heat and pressure, forming a uniform, rigid matrix that offers excellent depth filtration. Unlike traditional metal or polymer filters, this element combines high mechanical strength with outstanding chemical resistance, making it ideal for continuous operation in harsh conditions. Below, we detail its key features, technical specifications, and benefits to help you understand why it's a trusted choice for chemical processing plants worldwide.
- Exceptional Chemical Resistance: The phenolic resin matrix withstands a wide pH range (2-13) and is resistant to most organic solvents, acids, and alkalis, ensuring long service life even in aggressive media.
- High Pressure Capability: Rated for 10 Bar maximum operating pressure, this filter element can handle high-flow applications without deformation or collapse.
- Uniform Pore Structure: Sintering technology creates a consistent pore distribution, providing reliable filtration efficiency and high dirt holding capacity (up to 3-5 times that of surface filters).
- Thermal Stability: Operates effectively at temperatures up to 80°C (optional higher grades available upon request), suitable for many hot liquid filtration processes.
- Easy Maintenance: The filter element can be cleaned by backwashing or chemical cleaning, reducing replacement frequency and operational costs.
- Customizable Dimensions: Available in various lengths, diameters, and connection types (threaded, flanged, or custom) to fit standard or unique housings.
- Low Pressure Drop: Optimized design ensures minimal resistance to flow, saving energy and reducing pump workload.
- Environmentally Friendly: Phenolic resin is a non-toxic, inert material that can be safely disposed of or incinerated after use.

Frequently Asked Questions
Q1: What is the maximum temperature this filter element can withstand?
A: The standard operating temperature is up to 80°C (176°F). If your application requires higher temperatures (e.g., up to 120°C), we can provide a customized version using a modified resin formulation. Please contact us with your specific requirements.
Q2: Is the filter element resistant to strong acids like sulfuric acid or hydrochloric acid?
A: Yes, the sintered phenolic resin material is highly resistant to most acids, including sulfuric acid (up to 70% concentration), hydrochloric acid, and phosphoric acid, as well as many alkalis and organic solvents. However, we recommend testing with your specific chemical at the intended temperature and concentration to confirm compatibility, as performance can vary with extreme conditions.
Q3: How do I clean and reuse this filter element?
A: The element can be backwashed with clean water or a compatible solvent, or chemically cleaned using mild acids or alkalis (depending on the contaminant). Avoid using strong oxidizing agents or high-pressure water jets that may damage the structure. With proper cleaning, the element can be reused multiple times before replacement, depending on the application.
Q4: What is the typical lifespan of this filter element?
A: Lifespan depends on the solid load, chemical aggressiveness, and cleaning frequency. In many chemical processing applications, a single element can last 6-12 months or longer with regular backwashing. High dirt holding capacity means fewer replacements compared to surface-type filters. We can provide estimated life based on your specific process parameters.
Q5: Can I get custom dimensions or connection types for my existing housing?
A: Absolutely. We offer custom lengths from 5 inches to 60 inches, various outer diameters, and connection types including threaded (NPT/BSP), flanged, bayonet, or double open-end. Please provide your housing specifications or a drawing, and we will produce a compatible element.
Q6: Does the filter element comply with any food-grade or pharmaceutical standards?
A: Our standard sintered phenolic resin filter elements are made from materials that are generally considered safe for industrial chemical processing. For food-contact or pharmaceutical applications, we can provide elements manufactured with specific raw materials and processes that meet relevant regulations (e.g., FDA or EU food contact). Please inquire about your specific compliance requirements.
Q7: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is typically 50 pieces. For custom sizes, the MOQ may be higher (e.g., 100-200 pieces) depending on tooling and production setup. We also offer sample orders for testing and evaluation – please contact our sales team for details.
Q8: How is the filter element packaged for export?
A: Each element is individually wrapped in plastic to prevent moisture and contamination, then packed in sturdy corrugated cartons with foam inserts to prevent damage during transit. For large orders, we use wooden pallets or crates. We ensure packaging meets international shipping standards.
