Technologically and logistically unique
Market and technological expertise in the processing industryExtreme 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
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)

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:
- Radiamatic shaft sealing rings
- Butterfly valve seals
- Stuffing box packings
- Clamp seals
- Dairy pipe connections
- Flat seals
- O-rings and encapsulated O-rings
- Hygienic Usit rings
- Precision formed parts
For example, these sealing solutions are found in valves, pumps, hygienic design components, CIP/SIP systems, pipe connections and tablet presses.
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:
- Freudenberg Xpress – Turned seals and express service
- Laser marking technology
- Field tests on own test stand
- Damage analyses
- Logistics services – local warehousing, individual packaging, kitting, color marking
- Resistance testing
- Hygienic design
- Material development
- Product development
- Extrusion technology
- Friction optimization
The handbook for the process industry
All the important information on our products and our materials as well as technical background information can be found in our Technical Sealing Handbook for the Process Industry.
Sealing solutions specially developed for the process industry in accordance with hygienic design and materials with industry-specific approvals.
A FEP/PFA-encapsulated O-ring consists of an elastomer core and a seamless sealed cover.
Demanding applications in the process industry require specific know-how and well-founded materials expertise. Apart from a broad product range, Freudenberg also offers specific materials with international approvals such as FDA, USP Class VI, NSF and regulation (EU) 1935/2004, as well as seals based on hygienic design.
The Radiamatic® HTS II is a special PTFE variant of the Simmerring® product group. This high-performance radial shaft seal sets standards in the sealing of rotating shafts and spindles.
High performance materials for the extreme requirements in the Process Industry
The basis of high-tech sealing and vibration control technology solutions
Maintenance, Low volume, Prototyping. Fast delivery of sealing solutions with proven reliability.
The Hygienic Usit® from Freudenberg was developed especially for the process industry and is setting completely new purity standards.
The premium universal material for the processing industry. A wide variety of applications that are impressive right down the line: Fluoroprene XP is the universal sealing material for steam sterilization, aggressive CIP-/SIP-media and high-fat concentrations.
FKM (fluororubber) is a high-quality material that can be used in the entire processing industry.
Clamp seals make fast and secure flange connections in continuously operating equipment. Due to their symmetrical geometry, the clamp connections can be mounted and re-separated very easily.
Freudenberg Sealing Technologies offers specially manufactured flat gaskets in a wide variety of shapes – whether classically round or customized according to drawing – particularly fast and flexible.
With its outstanding qualities in critical media, our EPDM materials are the first choice for a wide variety of O-rings, formed parts and diaphragm applications in the food, beverage, pharmaceutical and chemical industries.
The Simmerring® is flexible, highly loadable and reliable in its operation. Freudenberg Sealing Technologies has now further developed Simmerrings® for use in the process industry – composed of materials approved for contact with foods.
In food and pharmaceuticals industries production today, everything revolves around the issue of purity.
The extractables study investigates the interactions between the pharmaceutical product and the elastomer.
Freudenberg Xpress - quality in record time
Sealing components made of elastomeric materials can have inherently high surface energies (tackiness) and a high coefficient of friction (COF).
