Wholesale High-Quality Polymer Melt Filter Elements Suppliers from China Factory - SUS 304 Candle Filtration Solutions Exporters, Companies
The melt filter element is an essential filtration device utilized extensively in the chemical fiber industry for processing polymer melts and other high-viscosity materials. This innovative product is designed to effectively eliminate solid impurities, such as carbonized particles and metal oxides, from the melt. By enhancing the purity of the polymer melt, it ensures the provision of high-quality raw materials for downstream processes and maintains the optimal functioning of the melt filtration system, Designed with efficiency in mind, the candle filter element is housed within a robust filter housing and features a compact design capable of accommodating 1 to 20 candles, based on the filter's size. Arranged vertically within the pressure vessel, this filter element efficiently processes liquids with low solid content. The candle filter not only facilitates high productivity but also enables easy discharge of bottom sediments, As a leading China factory and supplier of melt filter elements, we are committed to delivering superior quality products that meet the rigorous demands of the chemical fiber industry. Our melt filter solutions are engineered for reliability and effectiveness, establishing us as a trusted partner in your filtration needs
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
1
Effectively filters out gel particles, carbonized impurities, catalyst residues, dust and other tiny particles in the melt.
2
Enhances the mechanical properties and appearance of the product.
3
High dirt-holding capacity — can hold a large amount of pollutants before being completely clogged, significantly extending the replacement cycle.
4
Reduces downtime caused by replacing filters or cleaning equipment, improving the utilization rate and overall efficiency of the production line.
5
Provides stable and consistent filtration resistance, helping maintain the stability of melt pressure, flow rate and temperature for a more controllable and smoother production process.
6
High temperature and high pressure resistance — typically 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
Q
What materials are used in polymer melt candle filter elements?
Polymer melt candle filter elements are primarily made from SUS304 or SUS316L 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 maximum working temperature for these filter elements?
The polymer melt candle filter elements can operate at temperatures up to 350°C (≤350℃), making them suitable for high-temperature polymer melt filtration applications such as polyester and nylon fiber production.
Q
What filtration ratings are available for candle filter elements?
Candle filter elements are available in filtration ratings ranging from 1 to 200 microns, allowing customers to select the appropriate rating based on their specific polymer melt filtration requirements and impurity particle sizes.
Q
How do you clean and maintain polymer melt filter cartridges?
Most polymer melt filter cartridges need to be removed from their housings for cleaning. They are sterilized and washed thoroughly. Some systems support backwashing or CIP (Clean-In-Place) design. After cleaning, cartridges should be dried and sealed or vacuum-packed to prevent contamination before reuse.
Q
What industries use polymer melt candle filter elements?
