O-Ring white thin

70 EPDM 38596
New White High-Performance Material for the Process Industry

The new white high-performance material 70 EPDM 38596 from Freudenberg Sealing Technologies has been developed especially to meet the high demands of the process industry. The material is extremely well suited for manufacturing O-rings and sealing rings with simple cross-sections. It not only has excellent mechanical properties, but also very good resistance to standard cleaning media and steam. It is particularly well suited for contact with aqueous products and dairy products with a low-fat content. The very low extractables values are also an advantage that the material 70 EPDM 38596 offers.

Product Benefits

  • Reliable certification according to EU (Reg.) 1935/2004, EU (Reg.) 2023/2006 and FDA
  • Very good material for O-rings and sealing rings with simple cross-sections
  • Excellent mechanical properties
  • Very good resistance to standard cleaning media, which is why it shows similar to very good comparable resistance to the very proven black material 70 EPDM 291.
  • Excellent temperature resistance in steam (up to +160 °C)
  • Very low extractables values

Monitored Seals

Smart Seals

The Freudenberg Smart Seal opens up the possibility of predictive maintenance. With the Freudenberg Smart Seal, a seal continuously indicates its degree of wear. The information can be linked to plant data, enabling the creation of a "digital twin". It is also possible to predict when a seal needs to be replaced – an important capability for predictive maintenance and one of the core components of industry 4.0. The Freudenberg Smart Seal is the only system that enables wear measurement directly on the seal, which can significantly increase overall plant effectiveness.

Our experts will be happy to advise you on your individual requirements and how this innovative sealing solution can support you in terms of industry 4.0.

Product Benefits

  • Proactive planning of maintenance intervals
  • Avoidance of batch contamination and consequential damage
  • Reduction in the amount of personnel required for maintenance
  • Flexibility through individually adjustable intervention limits

In our video, you can see the Freudenberg Smart Seal using the example of an intelligent seal in a valve.
