Polymer Filter Used for Polymer Melt Filtration

The polymer filter elements are constructed with supporting layers and filter layers that pleated together. So it’s also called pleated metal filter. With supporting layer, the polymner filter elements could undertake the high pressure. With the pleated process, the filtration area of polymer filter elements is several times of usual candle filter. Because of this, it shorten the filter time and improve the filter effectiveness .

It’s ideal material for polymer filter on fibers, films and resins. The polymer filter elements are widely used for chemical fiber, textiles and plastic industries. We design a range of product to meet the diverse filtration, separation, and purification demand.


  • High flow rates. With the pleated process, polymer filter elements increase the filter area and dirt holding capacity. That reduces the differential pressure and save the filter cost.
  • Long on-stream life time. Our polymer filter elements are siutable for different application environment, including stainless steel, Hastalloy, Inconel, Nickel……. These material makes the filter an excellent mechanical strength, good corrosion resistant and high temperature. These help extend the service life and save cost.
  • Easy to clean. Through superheated steam, chemical cleaning, Ultrasonic cleaning and other method to clean the contamination. We have the skilled technical department to solve the critical cleaning problems to extend the filter on-stream lifetime of polymer filter elements
