Product Description

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

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 final product.
3

High dirt-holding capacity — can retain a large amount of pollutants before becoming fully clogged, significantly extending the replacement cycle.
4

Reduces downtime caused by replacing filters or cleaning equipment, improving production line utilization and overall efficiency.
5

Provides stable and consistent filtration resistance, helping maintain the stability of melt pressure, flow rate and temperature for a more controllable and smooth 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 (FAQ)

What materials are used to make polymer melt candle filter elements?

Polymer melt candle filter elements are primarily made from SUS304 or SUS316L stainless steel. The filter media consists of either stainless steel wire mesh or sintered stainless steel fiber, both of which offer excellent high-temperature resistance, corrosion resistance, and mechanical strength suitable for demanding melt filtration environments.

What filtration ratings are available for candle filter elements?

Candle filter elements are available in a wide filtration rating range of 1 to 200 microns, allowing them to be tailored for different levels of polymer melt purity requirements. Custom ratings can also be provided based on specific application needs.

What is the maximum operating temperature for these filter elements?

The polymer melt candle filter elements are designed to withstand working temperatures of up to 350°C, making them suitable for high-temperature polymer processing applications such as polyester melt extrusion and petrochemical refining.

How do I clean and maintain a polymer melt filter element?

Cleaning methods depend on the filtration system design. Some systems support backwashing or CIP (Clean-in-Place) procedures. For most filter elements, they need to be removed from their housings, sterilized, and thoroughly washed. After cleaning, they should be dried completely and then sealed or vacuum-packed to prevent contamination before reuse.

What industries commonly use polymer melt candle filters?

Polymer melt candle filters are widely used across multiple industries including petrochemical (refining and chemical production), metallurgy (hydraulic system filtration for rolling mills and continuous casting machines), and textile (purification of polyester melt during fiber drawing). They are also applied in pharmaceutical, food and beverage, and automobile manufacturing sectors.

What connector types are compatible with these candle filter elements?

The candle filter elements are compatible with a wide range of connector types including 222, 226, 215, M36, M28, M24, M22, and M20. Custom connector configurations can also be arranged to meet specific system integration requirements.
