The construction of the CPF candle filter is a testament to engineering precision. At their core, is the polymer filter element, a vital part engineered to efficiently trap contaminants and impurities. These filters bear a resemblance to candles, and are crafted from high-quality materials which are capable of withstanding the extreme temperatures and pressures encountered in polymer manufacturing. Crafted from materials like sintered metal or ceramics, the polymer filter element forms the foundation of all CPF candle filters. This core houses an intricate network of channels, forming a sophisticated filtration pathway.
The term polymer candle filter signifies precision and excellence in ensuring the purity of polymer products. CPF candle filters operate as polymer melt flows through them. Along this complex path, contaminants are captured, leaving behind only the pure polymer. It's a process that guarantees the final polymer product meets the strictest quality standards.
⚙️ Filter Media Options: The main filter layer of Pleated Filter primarily uses two materials — stainless steel wire mesh and stainless steel sintered fiber. Stainless steel wire mesh is woven from stainless steel wire, featuring smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no wire mesh falling off, and a long filtration cycle. Stainless steel sintered fiber is a porous deep filter material made of stainless steel fibers sintered at high temperature, featuring high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.

Frequently Asked Questions
Q What is a CPF candle filter and how does it work?
A CPF candle filter is a precision filtration device used in polymer manufacturing. It consists of a polymer filter element — typically made from sintered metal or ceramics — through which polymer melt flows. As the melt passes through the intricate channel network, contaminants are captured and only pure polymer exits, ensuring the final product meets strict quality standards.
Q What materials are used for the filter media in CPF candle filters?
The main filter media used in CPF pleated candle filters are stainless steel wire mesh and stainless steel sintered fiber. Both are made from SUS304 or SUS316L stainless steel, offering excellent corrosion resistance, high temperature tolerance, and long service life.
Q What is the filtration rating range available for CPF candle filters?
CPF candle filters are available with filtration ratings ranging from 1 to 200 microns, making them suitable for a wide variety of polymer melt filtration applications across different industries.
Q What are the maximum working temperature and pressure for these filters?
CPF candle filters can operate at temperatures up to 350°C, with an allowed pressure difference of 10 bar (14 psi). This makes them well-suited for the extreme conditions encountered in polymer and chemical fiber manufacturing environments.
Q Can CPF candle filter elements be cleaned and reused?
Yes. Candle filter elements made from 304L or 316L stainless steel are designed for repeated cleaning and long-term use. They are highly resistant to high temperatures and corrosive environments, making them a cost-effective and durable solution for polymer melt filtration.
Q What quality control measures are applied to CPF candle filters before shipment?
Every filter element undergoes rigorous bubble-point and air flow testing before shipment to verify product integrity and performance. Each batch is accompanied by a test certificate, and all elements are laser marked at the end fittings for easy identification and reliable after-sales traceability.
