The polymer melt filter cartridge 60×243 is a high-performance pleated wire mesh candle filter engineered specifically for polymer melt filtration in chemical fiber, textile, and plastic industries. This cartridge is designed to remove solid impurities such as carbide particles, gel layers, metal oxides, and other contaminants from high-temperature, high-viscosity polymer melts, thereby improving melt purity and ensuring consistent product quality.
Manufactured from high-quality 304 or 316L stainless steel or other metal woven cloth, the filter element is produced through precision spot welding, pleating, and pressing processes. The pleated design significantly increases the filtration surface area, enhancing dirt-holding capacity and extending replacement cycles. The filter features an outside-in flow configuration—polymer melt enters from the bottom and flows from outside to inside, with impurities trapped on the filter surface while clean melt passes through.

Cleanable and Reusable: The woven mesh construction supports thermal, ultrasonic, and solvent cleaning. Multiple cleaning cycles reduce long‑term consumables cost.
ISO 9001 Certified Quality: Raw material inspection, in‑process quality control, and final dimensional verification ensure consistent, reliable performance.
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.
