China Polymer Candle Filter Elements SUS 304 - Top Suppliers & Factory for High-Quality Filtration Solutions

Candle filters, resembling traditional candles, play a vital role in the filtration process during the production of polymers like plastics and chemical fibers. The Melt Filter Cartridge is essential for ensuring the removal of impurities from the polymer melt under challenging conditions, including high temperatures, high pressures, and high viscosity. This advanced filter not only guarantees the quality of the final product but also enhances production efficiency and safeguards downstream equipment, Manufactured by leading suppliers in China, our candle filter elements are housed within a robust filter housing, designed to accommodate between 1 to 20 filter candles, based on the specific requirements of your filtration system. With our trusted factory manufacturing process, you can rely on superior performance and durability for all your filtration needs

    Description
    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.

    Core Advantages of Melt Filters
    • 🔬
      1. Ensure High Purity and Uniformity of the Product

      It can effectively filter out gel particles, carbonized impurities, catalyst residues, dust and other tiny particles in the melt.

    • 💪
      2. Enhance the Mechanical Properties and Appearance of the Product

      Impurities are stress concentration points, which can reduce the strength, toughness and durability of the product. After removing impurities, the comprehensive mechanical properties of the product have been significantly improved.

    • ⚙️
      3. Enhance Production Continuity and Efficiency

      It has a high dirt-holding capacity and can hold a large amount of pollutants before being completely clogged, thereby significantly extending the replacement cycle. It has reduced the downtime caused by replacing filters or cleaning equipment, and improved the utilization rate and overall efficiency of the production line.

    • 📊
      4. Enhance Process Stability

      It provides stable and consistent filtration resistance, which helps maintain the stability of melt pressure, flow rate and temperature, making the entire production process more controllable and smoother.

    • 🔥
      5. High Temperature and High Pressure Resistance

      It is usually made of stainless steel (such as 304, 316L), Hastelloy and other metals.
