Food and drink industry:
When it comes to food and drinks it is important to pay close attention to the hygiene, durability and conformity. Seals can be used in a lot of ways. For the food and drink industry they need to have a high degree of purity and make it to the hygiene standards.
When filling beverages it is important to avoid aroma transfer. The sealing materials need to be able to withstand aggressive cleaning materials and fabrics. There are legal requirements the sealing must adhere:
EU (VO) 1935/2004
American FDA $ 177.2600
Chinese GB 4806
Hygienic Design Standards (European Hygienic Engineering and Design Group)
The EHEDG needs to make sore the seal is free from dead space and prevent contamination.
Specially made mixed like, 70 EPDM 291 or Fluoroprene are relevant. This is because they withstand the temperature alterations and aggressive media. The newest designs have the most innovative products, because of these designs they can be used in a wide range of applications. An example of this is the Radiamatic® HTS II. This is a reliable sealing that does not have dead space even under extreme applications.
