Our CPF Candle Filter Elements consist of metal pleated filters securely attached to candle holders, functioning as an efficient candle-like filtration unit. These porous metal filters are ideal for high-temperature and high-pressure applications in polymer processing. Specifically designed to remove impurities such as titanium dioxide, gels, and other solid residues, these filters are widely used in the chemical fiber, textile, and plastics industries. As a trusted China supplier and factory, we provide solutions suitable for monomer, pre-polymer, and polymer filter systems, ensuring optimal performance in your manufacturing processes.
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.
⚙️ 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
QWhat 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 shaped like a candle — made from sintered metal or ceramics. As polymer melt flows through the filter's intricate channel network, contaminants and impurities are captured, allowing only pure polymer to pass through and meet strict quality standards.
QWhat materials are used in the CPF candle filter element?
CPF candle filter elements are primarily made from SUS304 or SUS316L stainless steel. The filter media options include stainless steel wire mesh and stainless steel sintered fiber, both of which offer excellent temperature resistance, corrosion resistance, and long service life.
QWhat is the filtration rating range available for polymer candle filters?
Our polymer candle filters are available with filtration ratings ranging from 1 to 200 microns, making them suitable for a wide range of polymer melt filtration applications across various industries including chemical fiber manufacturing.
QWhat is the maximum working temperature and pressure for these filters?
The CPF candle filters are rated for a maximum working temperature of ≤350°C and an allowable pressure difference of 10 bar (14 psi), making them well-suited for demanding high-temperature polymer processing environments.
QWhat are the advantages of stainless steel sintered fiber over wire mesh in pleated filters?
Stainless steel sintered fiber offers higher porosity, better air permeability, stronger dirt holding capacity, and superior regeneration ability compared to standard wire mesh. Wire mesh, on the other hand, features smooth pores, easy cleaning, and no risk of wire falling off — making both materials suitable for different application needs.
QHow 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. A test certificate is provided with each shipment lot. All elements are also laser marked for traceability, and are manufactured from 304L or 316L stainless steel to ensure durability, cleanability, and suitability for high-temperature and corrosive environments.
