High Viscosity Polymer Candle Filter - Top China Suppliers and Factory for Melt Filtration Solutions

The melt filter element is an essential filtration device utilized in the chemical fiber industry, specifically designed for the filtration of polymer melts and other high-viscosity materials. Its primary role is to effectively eliminate solid impurities, including carbonized particles and metal oxides, ensuring the highest purity levels in the melt. By providing qualified raw materials for downstream processes, our melt filter element guarantees the seamless operation of the filtration system. As a leading factory in China, we pride ourselves on supplying top-quality melt filter elements that meet the demands of the industry. Trustworthy suppliers in China count on us for reliable, high-performance filtration solutions tailored to enhance production efficiency

    Description

    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.

    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
    Q What materials are used in the pleated candle filter?
    The pleated candle filter primarily uses two materials: stainless steel wire mesh (SUS304/316L) and stainless steel sintered fiber. Both offer excellent high-temperature resistance, corrosion resistance, and long service life for polymer melt filtration applications.
    Q What is the maximum working temperature for the polymer candle filter?
    The polymer pleated candle filter can withstand working temperatures of up to 350℃ (662°F), making it suitable for high-temperature polymer melt filtration processes in extrusion and spinning lines.
    Q What filtration ratings are available for the melt filter element?
    The filtration rating ranges from 1 to 200 microns, allowing customers to select the appropriate precision level based on their specific polymer melt filtration requirements and process conditions.
    Q What connector types are compatible with the polymer candle filter?
    The filter is compatible with a wide range of connector types including 222, 226, 215, M36, M28, M24, M22, and M20, ensuring easy integration into most existing filtration systems and housings.
    Q Can the polymer pleated candle filter be cleaned and reused?
    Yes. The stainless steel wire mesh version features smooth pores and easy-cleaning characteristics, while the sintered fiber version offers strong regeneration ability. Both types are designed for extended service life and can be cleaned and reused multiple times under proper maintenance.
    Q Can custom specifications be provided for specific applications?
    Absolutely. We can manufacture high-quality polymer pleated candle filters to meet your specific requirements, including custom filter lengths (16–60 inches), filtration ratings, connector types, and filter media to suit your unique polymer melt filtration application.
