Sintered filters made of porous plastics and metals

Porous sintered materials for filtration are composed of granules that are compressed together at high temperatures in a sintering process. During the production process, voids (pores) are created in the sintered material, allowing gases and, depending on pore size, liquids to pass through. Porous plastics are particularly interesting for gas filtration and in gas distribution systems (aeration systems). The filters used as plates, rods, or tubes are easy to clean after the filtration process, even when exposed to sticky media.

Sintered filters submerged in suspended particle-laden water do not become dirty because neither water nor electrolytes can penetrate the pores. Despite this, the gas flow remains high and consistently intense. Reichelt Chemietechnik provides porous plastic materials for filters in various material modifications. These include UHMW-PE (ultra-high-molecular-weight polyethylene), HDPE (high-density polyethylene), and chemically absolutely resistant PTFE (polytetrafluoroethylene, THOMAFLON), which can withstand temperatures up to +260°C. Explore sintered filters, plates, rods, and tubes in our product range.

Sintered filters as sintered plates

Metal fiber plates for filters

In addition to plastic filters, Reichelt Chemietechnik supplies sintered metal fiber plates made of stainless steel 1.4401 with a temperature limit of +500°C, as well as metal plates made of highly porous Cr-Ni steel, which can also withstand temperatures up to +500°C, even in an oxidizing atmosphere. These highly porous filters with metal sintered plates are BfR-compliant and contribute to food safety, feed safety, chemical safety, as well as product safety in manufacturing.

HDPE

Sintered plates made of microporous or porous HDPE are used for the filtration of gases, soot, and liquids, as well as for aeration, aeration, atomization, and fluidization. These semi-finished products are designed for continuous operation at temperatures of +82°C, noting that they have a very high density and are also hydrophobic. The filters are resistant to strong alkalis and acids, as well as alcohols, aliphatic hydrocarbons, and organic compounds.

Sintered tubes and discs

Tubes made of microporous or porous HDPE, as well as sintered discs made of porous high-density polyethylene, correspond to the field of application and technical parameters of sintered plates made of this plastic.

Sintered discs made of porous and sintered rods made of microporous PTFE, as well as square sintered rods as gas filters made of porous PTFE, are used for filtration and the filtration of gases and liquids. They are also used in gas introduction systems for aggressive media.

The discs and tubes made of PTFE are configured for temperature ranges or operating temperatures from -200°C to +260°C. They are highly resistant to all inorganic and organic media and have hydrophobic properties. In other words, the filter material is non-wettable. These sintered filters are suitable as atomization units, porous intermediate layers in process vessels, as well as pressure compensation elements in apparatus construction and process engineering when working with varying pressures and as building blocks in electrochemistry.

About manufacturing: Custom sintered filter solutions are also possible

The production of sintered plates, sintered rods, sintered tubes, and sintered discs requires a special technology. Granules made of PTFE, HDPE, LDPE, UHMW-PE materials are technologically fused together to form stable bodies of different shapes. The choice of granules and process parameters can be used to specifically influence the pore size of the porous sintered elements, depending on which particles are to be filtered.

Reichelt Chemietechnik is open to your ideas and can implement them, so we can offer you customized solutions that make your operations easier. Our engineering teams are open to any suggestions and view your problems as their special challenge. We are happy to assist you. Please call us if you need expert advice: 06221-31250.

Note on the term "Teflon® sintered plate":

The Teflon® brand name is a registered trademark for the material PTFE and is owned by DuPont. This designation may only be used by companies for their products that can demonstrate the exclusive use of original Teflon® granules from DuPont for the production of semi-finished products such as hoses, plates, rods, films, etc. We do not use the term "Teflon®" for our components. Instead, Reichelt Chemietechnik employs the wordmark THOMAFLON, which represents a similar group of fluoropolymers.
