These high-performance filters are perfect for high-temperature and high-pressure polymer processing applications in industries such as textiles, chemical fibers, and plastics. Manufactured in China, our candle filter elements effectively eliminate impurities, including titanium dioxide, gels, and other solid residues from polymer melts, Ideal for monomer, pre-polymer, or polymer filter systems, these filter elements are typically tubular and constructed from high-grade stainless steel mesh or stainless steel sintered mesh. Each element features a bottom cap and a threaded connector at the top for seamless integration into filter systems. Additionally, the outer surfaces of some tubes are crafted from perforated metal sheets, expanded metal, sintered metal, or porous ceramic, providing robust support for the filter media, As a leading supplier and factory in the filtration industry, we ensure our candle filter elements meet the highest quality standards, making them the ideal choice for your filtration needs

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 candle filter element is placed inside the filter housing (housing). It is a compact device that can typically hold 1–20 candles, depending on the size of the filter. The filter element is arranged vertically in the pressure vessel to filter liquids with low solid content. The candle filter allows high productivity, easy bottom sediment discharge.

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.

❓ Frequently Asked Questions (FAQ)
What is a candle filter element and how does it work?
A candle filter element is a tubular filtration device installed inside a filter housing. Polymer melt or liquid is forced through the filter under pressure, and impurities are captured by the filter media. The candle filter is arranged vertically in a pressure vessel, allowing efficient filtration of liquids with low solid content and easy discharge of bottom sediment.
What filter media materials are available for the pleated candle filter element?
The pleated candle filter element is available in two main filter media materials: stainless steel wire mesh (woven from SS wire, offering smooth pores, easy cleaning, and high temperature resistance) and stainless steel sintered fiber (a porous deep-filter material with high porosity, strong dirt-holding capacity, and excellent regeneration ability).
What is the filtration rating range for your polymer candle filter elements?
Our polymer candle filter elements offer a filtration rating range of 1 to 200 microns, covering a wide spectrum of filtration requirements for polymer melt and other industrial applications.
What is the maximum working temperature and pressure for the candle filter element?
The candle filter element supports a maximum working temperature of up to 350°C and an allowed pressure difference of 10 bar (14 psi), making it suitable for demanding high-temperature and high-pressure industrial environments.
How is the quality of each polymer filter element ensured before shipment?
Every polymer filter element undergoes rigorous bubble-point and air flow testing before shipment to verify product integrity and performance. A test certificate is provided with each shipment lot. Additionally, all elements are laser marked at the bottom of the end fittings for easy identification and traceability.
In which industries can the polymer melt candle filter element be used?
The polymer melt candle filter element is widely used across multiple industries, including petrochemical (refining and chemical production), metallurgy (hydraulic systems for rolling mills), textile (polyester melt filtration), electronics and pharmaceuticals (water and liquid purification), and thermal/nuclear power (lubrication and control system purification).
