Polymer candle filter cartridges introduction and advantage

2025-08-12

Polymer melt candle filter is a critical component used in the chemical fiber industry for Polymer Filtration. Polymer melt is the molten form of synthetic polymers, which is used to produce various types of chemical fibers like polyester, nylon, and acrylic.

The main purpose of a Melt Filter element is to remove impurities, such as solid particles and contaminants, from the polymer melt before it is further processed into fibers. These impurities can negatively affect the quality of the final chemical fibers and cause production issues like unevenness, defects, and reduced mechanical properties.

In the chemical fiber industry, such as polyester, polyamide, polypropylene production, melt filter core is the guarantee of fiber quality core components, its application key points are as follows:

1.Intercept to remove impurities

In the molten polymer gel particles, impurities, carbide catalyst residues (size usually > 20 microns) prevent spinneret congestion, reduce broken filament

2.Homogenize the melt

Stabilize the melt fluidity and enhance the continuity of spinning through a multi-layer filter screen structure (such as 5-7 layer gradient sintering)

Through material science innovation and structural optimization design, stainless steel melt filter elements have become the core guarantee for high stability and low-cost production in the chemical fiber industry. The melt filter elements produced by our company can operate stably in high-temperature and corrosive environments. Through high-precision processing procedures, the service life of the melt filter elements can be extended, and the production cost of chemical fibers can be reduced. This is promoting the upgrading of traditional spinning processes towards precision and intelligence.

Additionally, our company provides custom manufacturing services for melt filter cartridges. Available materials include SUS304/316, Hastelloy®, and other alloys, with filtration media options of stainless steel mesh or sintered metal mesh. We accept bespoke specifications for:
