The New Generation of EPDM Materials

EPDM materialsTheir outstanding performance in critical media makes Freudenberg’s new EPDM materials the first choice for a broad range of O-ring, molded part and diaphragm applications in the food and beverage and pharmaceutical industries, compliant with all essential national and international standards.

Knowing what counts: as the market specialist for demanding sealing applications in process industries, Freudenberg Process Seals has expanded its range of EPDM materials and optimized it for use in the most critical application scenarios, allowing us to offer you uncompromising functionality for smoothly running production processes in an even broader spectrum of applications.

In comparison to conventional EPDM compounds, the new EPDM displays considerably higher water steam resistance, in addition to its exceptional durability in CIP/SIP media (Cleaning-in-Place/ Sterilization-in-Place). Depending on the individual application and design, Freudenberg’s EPDM is available in the following hardness ratings:

  • 60 EPDM 290
  • 70 EPDM 291
  • 85 EPDM 292

Freudenberg recommends 70 EPDM 291 as the standard material, which can be employed e.g. as a reliable O-ring seal for static applications. This version can also be optimized for dynamic applications by means of a friction-reducing RFN™ coating.

Otherwise, the compound 85 EPDM 292 is the right choice for dynamic applications. Given its specific performance profile, 60 EPDM 290 is especially well-suited for use in diaphragms.

 Outstanding Performance in Critical Media

Water Steam CIP / SIP Media Ozone Resistance (40°C)
Up to 180°C (short-term to 210°)
(a substantially higher resistance
to water steam compared to
other EPDM compounds)
Very good resistance to nearly all
conventional cleaning media.
Cleaning at 82°C in CIP media and
sterilization at 149°C is possible
(3-A® Sanitary Standard Class II)
At 1000 pphm, EPDM 291 and
292 offer the highest level of
ozone resistance in comparison
with other elastomers

Certifications & Authorizations

Given its compliance with all essential national and international standards, EPDM materials can be universally employed nearly anywhere in the world.
