The DN100 Polymer Melt Filter Element is a high-performance filtration component specifically engineered for demanding polymer melt processing applications. With an outer diameter of 102 mm and a height of 250 mm, this filter element is designed to meet the rigorous demands of extruder systems where molten polymers must be continuously purified before downstream processes such as fiber spinning, film extrusion, and blow molding.
Manufactured with high-quality stainless steel components and capable of withstanding extreme operating conditions — working pressures up to 30 MPa and temperatures up to 300°C — this filter element delivers exceptional performance, long service life, and cleanable reusability, making it a cost-effective choice for high-value polymer processing across petrochemical, synthetic fiber, and plastic manufacturing industries .

The DN100 Polymer Melt Filter Element is engineered for critical polymer processing applications requiring absolute filtration, thermal stability, and long service life.
Primary Applications Include:
Fiber & Filament Spinning: Melt filtration prior to spinnerets for nylon (PA6, PA66), polyester (PET), polypropylene (PP), and other specialty fibers.
Sheet, Film, and Blown Film Extrusion: Protecting dies, improving clarity, and preventing defects in packaging films, agricultural films, and industrial sheets.
Compounding & Masterbatch Production: Removing gels, carbonized particles, and filler agglomerates to ensure uniform dispersion and product quality.
Precision Injection Molding: Ultra-clean melt for medical components, electronic parts, and high-quality consumer goods.
Hot Melt Adhesives: Filtration of molten adhesives to prevent nozzle clogging and ensure consistent application.
Recycling & Reprocessing: Removing contaminants from post-consumer and post-industrial polymer streams.
At Huahang Filter, we combine advanced material science with precision manufacturing to create filtration components that perform reliably under the combined assault of high temperature, high pressure, and aggressive chemistry. Our polymer melt filters are built not as commodities, but as integral, high-reliability components of your production line. Operating from our modern 26,000㎡ ISO-certified facility, we serve clients in over 120 countries, with exports accounting for more than 80% of our business.

Huahang Filter supports full customization of the Polymer Melt Filter Element and other melt filtration products:

Q: Is the polymer melt filter element cleanable and reusable?
A: Yes. All metal construction supports backwashing, thermal decomposition (burn‑off in a controlled furnace), and ultrasonic cleaning. The element can be reused many times, significantly reducing long‑term costs.
Q: Are polymer melt filters compatible with all extruders?
A: Most are compatible, but proper sizing and pressure drop considerations are necessary for each extruder type.
Q: How to select the right polymer melt filter element?
A: Consider polymer type, melt temperature, viscosity, filler content, and chemical resistance to choose the correct filter material and mesh.
Q: Can melt filters be used for filled or reinforced polymers?
A: Yes, but high filler content requires wear-resistant materials like sintered metal, Inconel, or ceramic filters.
