Market and technological expertise in the processing industry

Extreme temperature conditions, aggressive media, high hygienic standards and safety requirements – the demands on the food and beverage, chemical and pharmaceutical industries are unique technologically as well as logistically.

As a sealing partner with the processing industry, Freudenberg Sealing Technologies combines materials competency and the capacity to produce sealing innovations with the special know-how of a market specialist in process technology. The result is a product and service portfolio that is unmatched in the market.


Quality creates functional reliability

This combination of technological competence and industry-specific experience leads to flawless quality, high functional reliability and economically efficient seal management.

Among other things, this includes amongst others:

  • Tailor-made materials and product development
  • Logistical approaches that guarantee the rapid, cost-effective availability of components, even in small batches.
  • Services specifically oriented to the demanding technical and business needs of equipment manufacturers and operators in the processing industry: for example, market-specific, application-related consulting that includes verified evidence of stability before the launch of series production.

Important sealing materials for the process industry

Black and White Materials

The requirements of the processing industry begin with precise specifications of the material. One example of many: the specifications of the U.S. Food and Drug Administration (FDA). These stringent rules influence the research and development activities of an entire sector. It follows that the right seal material is the key to success in the processing industry. Clean sealing solutions based on hygienic design demand the highest possible materials expertise, which results in premium materials.

At Freudenberg Sealing Technologies, in-depth materials testing – among other things for hardness, changes in volume, (continued) tear resistance, tension, breaking elongation, compression set and density – form the foundation for materials development and selection tailored to a particular requirements profile. 

The most important sealing materials in the processing industry are 

  • EPDM (ethylene propylene diene rubber)
  • Fluoroprene® XP
  • FKM (fluororubber)
  • Simriz® (perfluoroelastomer)
  • NBR (acrylonitrile butadiene rubber)
  • HNBR (hydrogenated acrylonitrile butadiene rubber)
  • VMQ (silicone rubber)
  • PTFE (polytetrafluoroethylene)
  • PEEK (polyetheretherketone)
  • POM (polyoxymethylene), PA (polyamide) and PU (polyurethane)

An overview of special materials for the process industry – including links to the corresponding material data sheets – can be found here. In addition, an overview of the relevant approvals and certifications for the process industry can be found here.


Important sealing products for the processing industry

In the process industry, special types of seals are just as important as their materials in meeting exceptional hygienic requirements, such as hygienic design:

For example, these sealing solutions are found in valves, pumps, hygienic design components, CIP/SIP systems, pipe connections and tablet presses.


Industry-specific services

In addition to sealing solutions, the service approach is an important criterion for decision-making in the process industry. For example, it begins with the design of the equipment and seals and ends with customized packaging and express delivery options. Freudenberg Sealing Technologies offers numerous customizable services such as:
