Parker's HiFluor® FB for Hygienically Sensitive Applications
Be it in the production of food, pharmaceuticals and cosmetics or medical devices coming into contact with the human body, excellent purity and media resistance combined with a wide range of robust properties is always required of the materials used for the components in the manufacturing processes. Specifically for these challenging applications, Parker has developed a new sealing compound with very good mechanical properties and excellent permanent elasticity: HiFluor® FB V8991.
Fluoroelastomeric materials have proven their viability in chemical and food processing, cosmetics, pharmaceutical and life science applications involving non-polar solvents, aliphatic compounds, greases, oils and aromatic substances whenever the resistance of standard materials such as hydrogenated nitrile butadiene rubber (HNBR) and ethylene propylene rubber (EPDM) is no longer sufficient.
Innovative “Pure” Sealing Solution HiFluor® FB V8991
As a compound and seal manufacturer, Parker Prädifa, in the light of the growing demands made on sealing elements in the aforementioned markets, has developed a HiFluor® FB compound with very good mechanical properties and excellent permanent elasticity.
With its properties profile shown in Table 1, HiFluor® FB V8991 proves to be the compound of choice in hygienic and aseptic applications.
O-rings and molded parts made of the newly developed HiFluor® FB compound V8991 are also particularly well suited for use in direct contact with the food or pharmaceutical products. In addition, Parker Prädifa always attaches major importance to compliance with the laws and regulations in target markets when developing new compound solutions for chemical and process engineering. Particularly in processes requiring a high level of purity of the final product, the meantime between failure (MTBF) of the component used is very important. A sealing element that has been attacked by chemicals will release particles that may enter the food product or batch of pharmaceutical ingredients, making them unfit for consumption. This may result in major financial losses. Due to its proven very good media resistance, the HiFluor® FB compound is superbly suited for use in many food, pharmaceutical and life science applications.

Higher Process Quality, Productivity and Safety Thanks to HiFluor® FB V8991
After using seals made of HiFluor® FB V8991, customers in the food, beverage, pharmaceutical and life science sectors have confirmed that they were able to increase MTBF for repaired units by 300 percent. In addition to improving their process quality, customers were able to considerably increase their productivity and the safety of their products which, not least thanks to the sealing compound, are fully traceable.
