Candle Filter Cartridge Elements for Polymer Processing - China Suppliers and Factory for High-Performance Filtration

Candle Filter Elements are innovative metal pleated filtration units designed to enhance the efficiency of polymer processing in high-temperature and high-pressure environments. Manufactured by leading suppliers in China, these filter elements are essential for the chemical fiber, textile, and plastics industries, effectively removing impurities such as titanium dioxide, gels, and other solid residues from polymer melts. Our products are suitable for monomer, pre-polymer, and polymer filtration systems, Constructed from durable stainless steel mesh or sintered mesh, these tubular filter elements feature a cap at the bottom and a threaded connector at the top to ensure secure attachment to the core end. The outer surface can be made from perforated metal sheets, expanded metal, sintered metal, or porous ceramics, providing optimum support for the filter media. Trust in our factory to deliver high-quality Candle Filter Elements that meet your filtration needs

    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)
    Q What is a candle filter element and how does it work?
    A candle filter element is a cylindrical filtration device placed inside a filter housing. In operation, the polymer melt is forced through the filter media under pressure, trapping impurities and contaminants while allowing clean melt to pass through. The elements are arranged vertically inside a pressure vessel and are particularly effective for liquids with low solid content, allowing high productivity and easy sediment discharge.
    Q What materials are used in the manufacture of polymer candle filter elements?
    Our polymer candle filter elements are manufactured from SUS304L or SUS316L stainless steel. The filter media is available in two main types: stainless steel wire mesh (woven from stainless steel wire) and stainless steel sintered fiber (a porous deep filter material made by sintering stainless steel fibers at high temperature). Both materials offer excellent corrosion resistance, high-temperature tolerance, and long service life.
    Q What filtration ratings and sizes are available for candle filter elements?
    Our candle filter elements are available in filtration ratings ranging from 1 to 200 microns, with filter lengths from 16 to 60 inches (406.4–1524mm). A wide range of connector types is supported, including 222, 226, 215, M36, M28, M24, M22, and M20. Custom specifications can be accommodated upon request to meet specific application requirements.
    Q What are the maximum working temperature and pressure for candle filter elements?
    The candle filter elements are designed to operate at working temperatures up to 350°C (662°F), making them suitable for high-temperature polymer melt filtration processes. The maximum allowed pressure difference is 10 bar (14 psi). These specifications make them ideal for demanding industrial environments including petrochemical, textile, and power generation applications.
    Q What industries and applications are candle filter elements suitable for?
    Candle filter elements are widely used across multiple industries, including petrochemical (refining and chemical production), metallurgy (hydraulic systems of rolling mills and continuous casting machines), textile (polyester melt purification during drawing), electronics and pharmaceuticals (reverse osmosis water treatment, cleaning fluid filtration), and thermal/nuclear power (lubrication and speed control system purification). Their versatility and robust construction make them a preferred choice for demanding filtration tasks.
    Q How is the quality of each candle filter element ensured before shipment?
    Every polymer filter element undergoes rigorous quality control before shipment. Each unit is tested using the bubble-point and air flow methods to verify product integrity and performance. A test certificate is provided with each lot of shipment. Additionally, all filter elements are laser marked at the bottom of the end fittings for easy identification and traceability, enabling reliable after-sales service and support.
