Custom High Viscosity Polymer Candle Filter for Chemical Fiber Production - China Suppliers & Factory Manufacturer, Exporters
The polymer candle filter is an essential component for the chemical fiber industry, specifically designed for polymer melt filtration. In China, top suppliers and factories provide high-quality polymer melt filters that ensure the purity of synthetic polymers, such as polyester, nylon, and acrylic, These filters serve a critical purpose by effectively removing impurities, including solid particles and contaminants, from the polymer melt. This meticulous filtration process is vital to maintaining the quality of the final chemical fibers, preventing production issues like unevenness, defects, and diminished mechanical properties. Choose our polymer candle filters from reliable suppliers and factories in China to enhance your production efficiency and product quality
The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The filtered polymer melt then proceeds to the spinning process, where it is solidified into continuous filaments or staple fibers.
Regular maintenance and replacement of the melt filter element are important to ensure the continuous and efficient operation of the chemical fiber production process. This helps to avoid production downtime, improve product quality, and ensure the longevity of the filtering equipment.
Main Features
1Resistant to high temperature, high pressure and chemical corrosion.
2Excellent breathability, large dirt holding capacity, high strength, good sealing, long life, and can be cleaned and reused for repeated use.
3The folded filter area is 3–5 times that of the cylindrical type.
4Working temperature: -60 ~ 500℃.
5The maximum pressure difference the filter element can withstand: 10 MPa.
