Frequently Asked Questions
A sintered porous plastic filter disc is made from plastic powder. This powder, like polyethylene (PE), polypropylene (PP), or polytetrafluoroethylene (PTFE), is heated below its melting point. Then, it is compressed using a sintering process to create a porous structure. This structure allows liquid or gas to pass through while filtering out impurities and particulate matter, and has high durability and chemical stability.
Sintered porous plastic filter discs are lower cost and lighter weight than metal filter discs (such as stainless steel or bronze). They are suitable for lightweight designs and have stronger chemical compatibility with acids, alkalis, and organic solvents. However, metal filter discs have a wider temperature resistance range (-200 to 800°C) and are suitable for extremely high temperatures or specific corrosive environments. Plastic filter discs are more commonly used in water treatment, pharmaceutical, and food industries, while metal filter discs are more common in oil and gas and high-temperature chemical processing. Both materials have their own targeted advantages.
Of course you can. Sintered porous plastic filter discs are highly customizable, with adjustable shapes (such as discs, tubes, plates or cones), pore sizes, filtration accuracy, connection methods (such as threads, flanges or plug-ins), and hydrophilic or hydrophobic properties. Customization requires detailed specifications, such as filter media, flow rate, working pressure and temperature, and we can provide precise solutions based on these requirements.
The factors to consider when choosing a sintered porous plastic filter disc are:
- Filter media (chemical properties of liquid or gas)
- Required pore size and filtration accuracy (based on particle size)
- Working environment (temperature, pressure and chemical compatibility)
- Flow rate and pressure drop requirements
- Required shape and connection method (such as threads or flanges)
Communicating specific application requirements with our technical team can ensure a customized and efficient filtration solution.
Some sintered porous plastic filter discs use FDA-approved materials (such as high-density polyethylene or polypropylene), meet food safety standards, and are suitable for the food and beverage industry (such as juice and beer purification). In the pharmaceutical and biotechnology sectors, some products, such as BioVyon™, meet the sterile filtration requirements of EMA and FDA. Compliance is determined based on materials, manufacturing processes and certification requirements.
