Product Description

Description

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 features 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 sintered at high temperature, offering high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.

❓ 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 works by allowing polymer melt to flow through a filter element — typically shaped like a candle — where contaminants and impurities are captured along a complex network of channels, leaving only pure polymer to pass through.

Q What materials are used to make the polymer filter element?

The polymer filter element is primarily made from sintered metal or ceramics. The main filter layers use either stainless steel wire mesh (SUS304/316L) or stainless steel sintered fiber, both of which offer excellent temperature resistance, corrosion resistance, and long filtration cycles.

Q What is the filtration rating range available for CPF candle filters?

CPF candle filters are available in filtration ratings ranging from 1 to 200 microns, making them suitable for a wide variety of polymer melt filtration applications depending on the required purity level.

Q What are the maximum operating temperature and pressure for these filters?

The candle filter elements can operate at working temperatures up to 350℃ and are designed to withstand an allowed pressure difference of up to 10 bar (14 psi), making them suitable for demanding high-temperature and high-pressure polymer processing environments.

Q How is the quality of each polymer filter element verified before shipment?

Every filter element undergoes rigorous testing using both bubble-point and air flow methods before shipment. A test certificate is provided with each lot. Additionally, all elements are laser marked for easy identification and traceability, supporting reliable after-sales service.

Q Can the candle filters be cleaned and reused?

Yes. Candle filter elements made from 304L or 316L stainless steel are designed for repeated cleaning and long-term use. Their high-quality sintered fiber or wire mesh construction makes them ideal for regeneration, reducing operational costs in continuous polymer manufacturing processes.
