What is Polymer Filters?

Polymer is common substances in life and industry, such as PET, polyester fiber, polycarbonate, polyurethane, nylon, etc. It often carry a variety of useless particulates and pollutants, so the polymer filters have important effect in purifying polymer and ensuring the quality of melt.

There are continuous polymer filter, candle filter system, duplex filter and other equipment that can filter polymers. They all have strong metal housing and internally mounted filter media that enable efficient filtration of high-viscosity polymers for long periods of time.

Filson also provides components including filter cartridge, candle filter, leaf disc filter, spin package filter, extrusion screen and so on. The fine aperture and wear-resistant materials ensure that it shows high performance in polymer production, recycling or reprocessing.

Polymer Filters Types by Filtration Component

Pleated Metal Filter Cartridge

Compared with ordinary filter cartridge, Filson pleated filter cartridge has uniform and dense fold design to expand filtration area and increase dirt holding capacity. It has good permeability, allowing the polymer to pass through at high flow rates.

Polymer Candle Filter

Usually installed in candle filtration system, Filson polymer candle filter is suitable to capture impurities in polymer melt, such as gels, textile fibers, wood and so on. It has porosity of up to 85% , which can maintain superior performance at high flow rate.

Leaf Disc Filter

Designed to be standard circles, Filson leaf disc filter has fast filtration speed to avoid polymer from being degraded because of the long residence time. Its filter accuracy ranges is from 0.5 micron to 200 microns for deep purification of the polymer.

Using stainless steel, aluminum, copper and other metals made of woven mesh or fiber mesh, Filson spin pack filter exhibits a variety of shapes, such as round, square, oval, semicircle, etc., It also has metal rotating wrap edges that provide stable structure.

Having flat, twill, Dutch or other woven screens types, Filson extruder screen is especially suitable for high-viscosity polymer melts to remove impurities by extrusion process. Compact structure and accurate aperture ensure smooth and efficient operation.

Filson Polymer Filters Benefits

Durable Quality

The housing of Filson polymer filter is 100% metal, with high temperature resistance, corrosion resistance and wear resistance to long use without being damaged.

Complete Types

Filson designs and produces various polymer filters including continuous filter, candle filtration system, duplex filter and their accessories to meet diverse demands.

Simple Operation

With advanced PLC control screen, Filson polymer filtration equipment realizes automated operation, which greatly reducing difficulty of use and saving labor costs.

Good Integrity

Filson uses laser cutting or welding technology to fabricate polymer filters, with good sealing and standard specifications. Rigorously tests ensure no leakage during filtration.

Advantages of Filson Polymer Filters

  • Continuity: Both the continuous polymer filter and double cylinder filter can continuously filter polymer melt. The former can discharge filter cake while filtering polymer, while the latter has two filter cartridges for filtering alternately.
  • Compatibility: The filter medias of Filson polymer filter are high purity metals, like stainless steel, aluminum, copper, etc., has excellent chemical inertness to be compatible with almost polymer melts, and is able to filter high viscosity samples.
  • Efficiency: Filson polymer filter has wide pore size range with minimum aperture as low as 0.5 microns, which enables fine filtration of polymer melts with filtration efficiency of up to 99.9%. It also has good permeability to speed up melt filtration speed.

Polymer FiltersFAQ Guide

What Impurities Does The Polymer Filter Capture in Polymer?

What Impurities Does The Polymer Filter Capture in Polymer

Polymers need to be heated to molten state during production, recovery, or reprocessing, therefore, they will inevitably be mixed with many impurities, such as sand, pollen, dust, metal particles, unmelted polymers, catalyst residues, etc.

What are The Functions of Polymer Filter?

By capturing the vast majority of impurities in polymer melts, polymer filters can guarantee the quality of finished polymer products.

If used as a pre-filter, it improves the downstream work efficiency. It also cleans up efficiently for complex polymer products such as microfibers or thin films. In addition, it protects and extends the life of polymer processing instruments.

What are The Main Applications of Polymer Filter?

Filson polymer filter is very compatible with various polymers, so it can be used in purification and filtration of various polymers, such as PET, polyester fiber, polycarbonate, polyurethane, nylon as so on.

What are The Advantages of Duplex Filter?

The advantage of duplex filter is the ability to continuously filter polymers and without terminal operation for replacement or cleaning.

Since it has two filter chambers, they do not run simultaneously but are alternately filtered, switching to a second filter chamber for continuous filtration process when one needs to be cleaned or replaced.

What is The Working Principle of Extrusion Screen Filtering Polymer?

Polymer melt is mostly highly viscosity and require external forces to pass through filter screen, so the extrusion screen is designed to facilitate melt flow and through the mesh. In this process, contaminants in melt are captured and pure melts pass to downstream equipment.
