Designed for high-temperature and high-pressure polymer processing applications, these porous metal filters are essential for the chemical fiber, textile, and plastics industries. They effectively eliminate impurities such as titanium dioxide, gels, and other solid residues from the polymer melt, making them suitable for monomer, pre-polymer, or polymer filter systems. As a leading factory and suppliers in China, we guarantee the reliability and efficiency of our CPF candle filters to enhance your production capabilities
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.

Frequently Asked Questions (FAQ)
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 contains 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 inside the filter, contaminants and impurities are captured, leaving only pure polymer output that meets strict quality standards.
Q
What materials are used in CPF candle filter elements?
CPF candle filter elements are primarily made from SUS304 or SUS316L stainless steel. The filter media options include stainless steel wire mesh (woven) and stainless steel sintered fiber (porous deep filtration material). Both materials offer excellent corrosion resistance, high-temperature tolerance, and long service life.
Q
What filtration ratings are available for polymer candle filters?
Our polymer candle filters are available in filtration ratings ranging from 1 to 200 microns, covering a wide range of polymer melt filtration requirements. The stainless wire mesh table provides detailed mesh specifications to help you select the right filtration rating for your application.
Q
What are the maximum operating temperature and pressure for these filters?
The CPF candle filters are designed to operate at working temperatures up to 350℃ and can withstand an allowed pressure difference of 10 bar (14 psi). These specifications make them suitable for demanding polymer melt and chemical fiber processing environments.
Q
What quality control measures are applied to each candle filter element?
Every filter element undergoes rigorous bubble-point and air flow testing prior to shipment. Each unit is also laser marked at the bottom of the end fittings for full traceability. A test certificate is provided with every shipment lot to ensure product integrity and support reliable after-sales service.
Q
Can CPF candle filters be customized to specific requirements?
Yes. We offer high-quality polymer pleated candle filters in a variety of lengths (16–60 inches), connector types (222/226/215/M36/M28/M24/M22/M20), and filtration ratings to meet your specific polymer melt filtration application requirements. Custom configurations are available upon request.
