China High Viscosity Polymer Candle Filter for Melt Filtration - Leading China Suppliers & Factory Manufacturer, Company
The polymer candle filter is an essential component in the chemical fiber industry, specifically designed for polymer melt filtration processes. This filter plays a critical role in ensuring the quality of synthetic polymers, which are used to create a variety of chemical fibers, including polyester, nylon, and acrylic
The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The filtered polymer melt then proceeds to the spinning process, where it is solidified into continuous filaments or staple fibers.
Regular maintenance and replacement of the melt filter element are important to ensure the continuous and efficient operation of the chemical fiber production process. This helps to avoid production downtime, improve product quality, and ensure the longevity of the filtering equipment.
Main Features
🔥Resistant to high temperature, high pressure and chemical corrosion.
✅Excellent breathability, large dirt holding capacity, high strength, good sealing, long life, and can be cleaned and reused for repeated use.
📐The folded filter area is 3–5 times that of the cylindrical type.
🌡️Working temperature: -60°C to 500°C.
💪The maximum pressure difference the filter element can withstand: 10 MPa.

Frequently Asked Questions
Q
What is a polymer candle filter element and how does it work?
A polymer candle filter element is a cylindrical or pleated filtration component installed in the extrusion line of chemical fiber production. The polymer melt is forced through the filter media under pressure, which traps and removes solid impurities and contaminants. The purified melt then moves on to the spinning process to form continuous filaments or staple fibers.
Q
What materials are used to manufacture the melt filter element?
The filter element is made from SUS304 or SUS316L stainless steel. The filter media consists of metal sintering mesh or stainless steel wire mesh, both of which offer excellent resistance to high temperatures, high pressures, and chemical corrosion.
Q
What filtration ratings are available for the polymer candle filter?
The polymer candle filter element is available in filtration ratings ranging from 1 to 200 microns, allowing customers to select the appropriate level of filtration precision based on their specific polymer melt processing requirements.
Q
Can the melt filter element be cleaned and reused?
Yes. The melt filter element is designed for cleaning and repeated reuse. Its high strength construction and excellent sealing properties ensure that it maintains performance after multiple cleaning cycles, helping to reduce operating costs and minimize production downtime.
Q
What are the maximum working temperature and pressure for these filter elements?
The filter element can operate within a working temperature range of -60°C to 500°C (with melt filtration applications typically rated up to 350°C). The maximum allowable pressure difference is 10 MPa, making it suitable for demanding high-pressure polymer melt filtration environments.
Q
Can custom sizes and specifications be provided for specific filtration machines?
Yes. In addition to standard sizes (such as Φ35 and Φ50 diameter candle filters in various lengths), custom polymer pleated candle filters can be manufactured to meet specific requirements. Multiple connector types are supported including 222, 226, 215, M36, M28, M24, M22, and M20, ensuring compatibility with a wide range of melt filtration machines.
