China Polymer Melt Filter Elements SUS 304 - High-Quality Suppliers & Factory for Efficient Filtration Solutions
Description
The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The main filter layer of Pleated Filter mainly uses two materials: stainless steel wire mesh and stainless steel sintered fiber. Stainless steel wire mesh is woven from stainless steel wire. Its pleated filter has the characteristics of smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no wire mesh falling off, and long filtration cycle. Stainless steel sintered fiber is a porous deep filter material made of stainless steel fibers sintered at high temperature. Its pleated filter has the characteristics of high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.

Core Advantages of Polymer Melt Filters
-
1It can effectively filter out gel particles, carbonized impurities, catalyst residues, dust and other tiny particles in the melt.
-
2Enhance the mechanical properties and appearance of the product.
-
3It has a high dirt-holding capacity and can hold a large amount of pollutants before being completely clogged, thereby significantly extending the replacement cycle.
-
4It has reduced the downtime caused by replacing filters or cleaning equipment, and improved the utilization rate and overall efficiency of the production line.
-
5It provides stable and consistent filtration resistance, which helps maintain the stability of melt pressure, flow rate and temperature, making the entire production process more controllable and smoother.
-
6High temperature and high pressure resistance. It is usually made of stainless steel (such as 304, 316L), Hastelloy and other metals.

How to Clean Industrial Filter Cores?
Industrial fine filters are widely used in industries such as pharmaceutical, chemical, ink and paint, food and beverage, automobile manufacturing, cement industry, petroleum, oil refineries, petrochemical, etc. It is important to clean these filter cartridges to ensure that they filter consistently over a long period of time.
Industrial filter cores provided by Song Phung have high dirt holding capacity, are easy to install, clean and maintain. The fine filter element is sturdy, has a solid quality core and has well-formed layers, so cleaning and installing them is very easy.
Some filtration systems allow backwashing and have a CIP system design. But most have to be taken out of their shells, sterilized and washed. When not in use, these cleaned filter cartridges are dried and sealed or vacuumed to prevent contamination or wear.
❓ Frequently Asked Questions (FAQ)
Q What materials are used in polymer melt candle filter elements?
Polymer melt candle filter elements are primarily made from SUS304 or 316L stainless steel. The filter media includes metal sintering mesh and stainless steel wire mesh, both of which offer excellent corrosion resistance, high temperature tolerance, and long service life.
Q What is the filtration rating range for candle filter elements?
The filtration rating ranges from 1 to 200 microns, making them suitable for a wide variety of polymer melt filtration applications depending on the level of purity required.
Q What is the maximum working temperature of the polymer melt filter?
The polymer melt candle filter elements can withstand working temperatures of up to 350°C, making them suitable for high-temperature polymer processing environments such as extrusion and fiber spinning lines.
Q How do I clean and maintain industrial candle filter elements?
Cleaning methods vary by system. Some filtration systems support backwashing with a CIP (Clean-In-Place) design. Others require removing the filter from its housing, sterilizing, and washing it manually. After cleaning, the filter should be dried and sealed or vacuum-packed to prevent contamination before reuse.
Q What industries can benefit from using polymer melt candle filters?
Polymer melt candle filters are widely used across multiple industries including petrochemical (refining and chemical production), metallurgy (hydraulic system filtration in rolling mills), and textile (polyester melt purification during fiber drawing). They are also applicable in pharmaceutical, food and beverage, automotive, and other manufacturing sectors.
Q Can custom specifications be provided for polymer melt candle filters?
Yes. Custom specifications are available to meet specific application requirements. Filter length can range from 16 to 60 inches (406.4–1524 mm), and connector types include 222, 226, 215, M36, M28, M24, M22, and M20. Please contact us with your specific requirements for a tailored solution.
