What is Porous Plate

Filson porous plate is formed by sintered particle porous materials, including bronze, aluminum, PP, PE, etc. After sintering process, it enjoys porous structure, which composes of tortuous interconnected pathways and minimal pores.

Its adjustable pore size characteristic gives many advantages to Filson porous plate, such as greater pore size, controlled flow of gases and liquids, as well as excellent filtration of fine particles, so it can be used across all market area and applications.

Further, Filson porous plate is cutting by unique techniques, which ensures our product has clean cut and well defined edges. Also, it is durable to suit almost any operating environment and conditions.

Porous Metal Plate Categories

Porous Bronze Sheet

After vacuum sintering process, Filson porous bronze sheet offers great resistance to most corrosive fluids and elevated temperature. Also, thanks to its high particles removal rate and adjusted pore size, our product is widely used as flame arrestor, high purity filters, setters, etc.

Porous Aluminum Plate

Filson porous aluminum plate features with many tiny pore inside and is superior rigidity, hence it delivers excellent impact strength and sound absorption capacity. Also, it is light weight than other porous metal plate, giving little energy consumption when heating up.

Porous Stainless Steel Plate

Filson stainless steel plate, alternatively called sintered stainless steel sheet, is formed by 100% stainless steel structure, hence our product offers excellent mechanical strength. With uniform pore distribution, it possesses high air permeability.

Porous Plastic Sheet Types Categories (4)

  • Porous Polypropylene Sheet
    Mainly formed by high dense polypropylene materials, Filson porous polypropylene sheet possesses excellent resistance to strength, chemicals and high temperature, as well as inert to most acids, alkali and organic solvents.
  • Porous PTFE Sheet
    Filson porous PTFE sheet is workable in extreme heat up to 260°C, and compare to other porous materials, which are easily fail in acid, alkali and solvent environment, it offers the ability to work in harsh conditions. Also, due to its non-adhesive, contaminants do not easy adhere to surface.
  • Porous Polyethylene Sheet
    With uniform porosity and precision machining, Filson porous polyethylene sheet offers superior filtration capacity while maintaining excellent flow for gases and liquids. Also, it can be cut, sawed, formed, machined and welded into any specifications based on your requirement.
  • Porous Glass Disc
    Goes through sintering process under high temperature, Filson porous glass disc forms porous and robust structure, which has low risk of shedding. With hydrophobic property, it enjoys low solution absorption, hence it is a proper solution for chemically clean and sterile.

Porous Plate FAQ Guide

What is Porosity?

Porosity is the ratio of open area in porous plate compared to its total volume. Generally, a porous plate with high porosity enjoys more open structure and higher flow rate. Combining both of the two to increase efficiency.

1. What is Porosity


What is Porous Plate Making Process?

Filson porous plate is created by the sintering process. The sintering process utilizes combination of heat and pressure to make the materials together. The purpose of sintering process is not to melt or transform the properties of materials, however, is to create customized porous plate based on customer’s need.
