Trelleborg’s seal, bearing materials conform to latest version of 3-A Sanitary Standard

Trelleborg’s Turcon® MF6 and Zurcon® Z431 PEEK™ seal and bearing materials have third-party verified declaration of conformance to the latest version of 3-A Sanitary Standard 20-27. Capable of withstanding high temperatures and the cleaning regimes used in food and beverage manufacturing, these compounds provide excellent tribological and sealing capabilities, extending seal and bearing life in hygienic dynamic applications.

Suitable for a wide range of seal profiles, scrapers and wear rings, Turcon® MF6 is part of the Trelleborg Sealing Solutions Turcon® MF range of polytetrafluoroethylene (PTFE) based sealing materials formulated for food contact, pharmaceutical and medical applications. The new Zurcon® Z431 PEEK™ is ideal for valve and bearing applications.

“As far as we know, we are the only seal and bearing supplier who has passed a third-party verification inspection for the 3-A Sanitary Standard number 20-27 for thermoplastic materials,” says Steven Farnsworth, food, beverage and pharmaceutical segment manager for Trelleborg Sealing Solutions Americas.

The Turcon® MF6 and Zurcon® Z431 PEEK™ materials passed 3-A cleanability response and product immersion tests according to 3-A Sanitary Standard number 20-27. This is in addition to passing migration tests for aqueous, acidic and fatty foods in repeated contact according to directive 2002/72/EC as well as sensory tests passed at 90 cm2 per liter/52.8 in2 per gallon surface/volume ratio at +95°C/+203°F for 30 minutes and FDA extraction tests according to 21CFR177.2415. Turcon® MF6 compound is listed by NSF International as conforming to the requirements of NSF/ANSI Standard 51-Food Equipment Materials.
