Bio-hygienic - Milkcouplings

The growth of bacteria, fungi and yeast on and around rubber seals forms a substantial threat in food safety.

HNBR-based rubber, which has been processed with Bio-hygienic, a silver-based biocide.

The bacteria or microbes make contact with the sealing ring,
The bacteria absorb the free silver ions on the surface of the sealing ring,
The silver ions destroy the bacteria/microbes by breaking down their cell walls.

The silver ions on the outside of the sealing rings remain active even after several washes
The silver ions are released in areas that are hard or impossible to access with classical detergents (e.g.: hairline cracks in the seals)
The Bio-hygienic additive has been approved by a number of major institutions:
- FDA: Food and Drug Administration
- EPA: Environmental Protection Agency
- FIFRA: Federal Insecticide, Fungicide and Rodenticide Act
- EFSA: European Food Safety Agency
Temperature resistance: -35 to +150°C
Steam resistance to 150°C
Superior resistance to general oils and greases compared to NBR,
Superior aging resistance compared to NBR,
Optimal sealing properties,
Yellow colour to facilitate recognition,

It is also possible to produce alternative types of sealants and/or qualities using Bio-hygienic additive, e.g.:

We also produce customized rubber seals with identical microbiocidal properties from 25 m using TPE (EPDM/PP).
