Freudenberg Sealing Technologies has developed its Simmerring seals in two new materials, making them suitable for food industry applications.
The Freudenberg Simmerring is designed for the sealing of rotating shafts and is already used in many different sectors and applications. Simmerring products in the B2PT design are now produced from a newly developed material, Quantum PTFE F18245 and with a housing manufactured from 1.4571 (V4a) stainless steel. Here, the PTFE deployed has been created specifically for direct food contact. Approvals are anticipated shortly under FDA 21 CFR 177.1550 und EC 10/2011.
In addition, Freudenberg Sealing Technologies has developed the Hygienic BlueSeal, the first dead-space-free version of the Simmerring. This hygienic shaft seal ring has a forward-mounted lip featuring geometry that avoids hard-to-clean areas, which prevents bacteria build-up and subsequent process contamination. Hygienic BlueSeal also makes use of the Quantum PTFE F18245 material.
The second new material development for Simmerring is 75 Fluoroprene XP 45, which aids secure attachment to metal. This highly fluorinated material already has the required approvals and certificates under EC 1935/2004, EC 2023/2006 and FDA 21 CFR 177.2600. The complete encasement of the Simmerring with 75 Fluoroprene XP 45, means it can be used in many food and beverage applications.
