China Suppliers Factory: High-Efficiency Polymer Candle Filter Elements SUS 304 for Melt Filtration
Description
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 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.

❓ Frequently Asked Questions (FAQ)
Q What materials are used in pleated candle filters?
Pleated candle filters primarily use two materials: stainless steel wire mesh and stainless steel sintered fiber. The raw material is typically SUS304 or SUS316L stainless steel, offering excellent corrosion resistance, high temperature tolerance, and long service life.
Q What filtration ratings are available for candle filter elements?
Our candle filter elements are available in filtration ratings ranging from 1 to 200 microns, making them suitable for a wide variety of polymer melt filtration and industrial liquid filtration applications.
Q What is the maximum working temperature for these melt filters?
The pleated candle filters can withstand working temperatures of up to 350℃, making them ideal for high-temperature polymer melt filtration processes in petrochemical, textile, and other industries.
Q Can the candle filters be customized to specific dimensions or connector types?
Yes. We offer candle filters in lengths from 16 to 60 inches (406.4–1524 mm) and support multiple connector types including 222, 226, 215, M36, M28, M24, M22, and M20. Custom specifications are available to meet your unique application requirements.
Q How do pleated candle filters improve production efficiency?
Thanks to their high dirt-holding capacity, pleated candle filters can accumulate a large amount of contaminants before requiring replacement. This significantly extends the filter replacement cycle, reduces production downtime, and improves the overall efficiency of the production line.
Q In which industries are polymer pleated candle filters commonly used?
Polymer pleated candle filters are widely used across multiple industries including petrochemical, metallurgy, textile (polyester melt filtration), electronics, pharmaceuticals, thermal power, and nuclear power plants — anywhere that demands reliable high-temperature, high-pressure liquid filtration.
