ODM High-Quality Polymer Candle Filter for High Viscosity Substances - China Suppliers and Factory Solutions Manufacturers, Supplier
The polymer candle filter is an essential component in the chemical fiber industry, specifically designed for polymer melt filtration processes. Manufactured in China, these filters are vital for ensuring the highest quality of synthetic polymers used in producing various 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: -60-500℃.
The maximum pressure difference the filter element can withstand: 10MPa.

Frequently Asked Questions (FAQ)
Q:
What is the function of the melt filter element in chemical fiber production?
The melt filter element is installed in the extrusion line to force the polymer melt through the filter, effectively removing impurities before it proceeds to the spinning process where it solidifies into fibers.
Q:
What are the main raw materials and media used in these filter elements?
The filter elements are made of high-quality SUS304 or SUS316L stainless steel. The filter media consists of metal sintering mesh and stainless steel wire mesh, providing high strength and excellent filtration ratings from 1 to 200 microns.
Q:
What temperatures and pressures can the polymer candle filter withstand?
These filters are highly resistant to extreme conditions. They can operate in temperatures ranging from -60℃ to 500℃ (with a standard working temp limit of ≤350℃) and can withstand a maximum pressure difference of up to 10MPa (10 bar/14psi).
Q:
Why is a folded filter design better than a standard cylindrical one?
The pleated or folded design increases the effective filtration area by 3 to 5 times compared to a standard cylindrical type. This significantly improves breathability, capacity, and overall longevity.
Q:
Can these melt filter elements be reused?
Yes. Thanks to their robust stainless steel construction, these filters feature excellent durability and sealing properties, allowing them to be cleaned and reused multiple times.
Q:
Are custom sizes and specifications available for specific machines?
Yes, high-quality polymer pleated candle filters can be customized to meet your specific polymer melt filtration application requirements. Standard sizes like Φ35 and Φ50 are also available for popular filtration machines.
