Wholesale China Polymer Candle Filter Elements SUS 304 - High-Quality Filtration from Reliable Suppliers and Factory Manufacturers, Suppliers
Candle filters, named for their candle-like shape, play a vital role in the polymer production process, particularly for plastics and chemical fibers. The Melt Filter Cartridge is an essential component that efficiently and continuously removes impurities from the melt, even under challenging conditions of high temperatures, high pressures, and high viscosities. This capability ensures the quality of the final product, enhances production efficiency, and protects downstream equipment, Our candle filter elements are designed to fit snugly within a filter housing, providing a compact solution that can accommodate anywhere from 1 to 20 candles, depending on the filter size. As a trusted China supplier, our factory specializes in manufacturing high-quality melt filter cartridges tailored to meet your filtration needs. Choose our products to guarantee optimal performance and reliability in your polymer production processes
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 melt filters
1. Ensure high purity and uniformity of the product:It can effectively filter out gel particles, carbonized impurities, catalyst residues, dust and other tiny particles in the melt.
2. Enhance the mechanical properties and appearance of the product:Impurities are stress concentration points, which can reduce the strength, toughness and durability of the product. After removing impurities, the comprehensive mechanical properties of the product have been significantly improved.
3. Enhance production continuity and efficiency:It has a high dirt-holding capacity and can hold a large amount of pollutants before being completely clogged, thereby significantly extending the replacement cycle. It has reduced the downtime caused by replacing filters or cleaning equipment, and improved the utilization rate and overall efficiency of the production line.
4. Enhance process stability:It 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.
5. High temperature and high pressure resistance:It is usually made of stainless steel (such as 304, 316L), Hastelloy and other metals.
Application Areas
1. PetrochemicalRefining, chemical production and separation and recovery of intermediate products.
2. MetallurgyUsed for filtration of hydraulic systems of rolling mills and continuous casting machines.
3. TextilePurification and uniform filtration of polyester melt during the drawing process.
4. Electronics and pharmaceuticalsPre-treatment and filtration of reverse osmosis water and deionized water, pre-treatment and filtration of cleaning fluid and glucose.
5. Thermal power and nuclear powerPurification of lubrication systems, speed control systems, bypass control systems of gas turbines and boilers, purification of water supply pumps, fans and dust removal systems.
Frequently Asked Questions (FAQ)
Q1: What are the main materials used for the pleated filter layer?
The main filter layer of the pleated filter primarily uses two materials: stainless steel wire mesh (woven from stainless steel wire) and stainless steel sintered fiber (a porous deep filter material sintered at high temperature).
Q2: What are the primary differences between stainless steel wire mesh and sintered fiber media?
Stainless steel wire mesh features smooth pores, easy cleaning, high temperature/corrosion resistance, and zero mesh shedding. Stainless steel sintered fiber offers high porosity, good air permeability, exceptional dirt holding capacity, and strong regeneration abilities.
Q3: What are the standard operating limits and sizes for these candle filter elements?
They support a working temperature of up to 350℃ and an allowed pressure difference of 10 bar (14psi). The standard length ranges from 16 to 60 inches (406.4-1524mm) with filtration ratings from 1 to 200 microns.
Q4: How do melt filters improve production efficiency?
Melt filters have a high dirt-holding capacity that extends replacement cycles. This reduces downtime caused by filter replacements and cleaning, thereby increasing the overall utilization and efficiency of the production line.
Q5: Can these candle filters be customized for specific applications?
Yes. High-quality polymer pleated candle filters can be customized in terms of sizes, materials (SUS304/316L), and connector types (such as 222, 226, 215, M36, M28, M24, M22, M20) to meet specific polymer melt filtration applications.
