Developed to Standard
to the European Community and KTW across the Atlantic, a range of regulatory bodies create legislation, regulations and standards to give guidance for the processes that make the food that we eat and the liquids we drink. They aim to create a regulatory environment that protects consumers and results in high quality products. But, with changing regulations and different standards across the globe, how do manufacturers keep up? That’s a question that Trelleborg Sealing Solutions aims to answer for its customers.
“In general, we’re seeing regulations becoming more strict globally, and new legislation being introduced in emerging markets” says Eberhard Baisch, Polymer Laboratory Manager for Trelleborg Sealing Solutions in Stuttgart, Germany. “Our material development laboratories work together globally to stay ahead of the changing market conditions”.To support these changing standards, Trelleborg Sealing Solutions has developed new compounds, such as the new EPDM compounds, E75F1 and E85F1, which offer a number of benefits to food and beverage manufacturers.
- Replaces the guidelines from 2011, and is recommended for any elastomers in contact with drinking water
- Does not govern thermoplastic elastomers (TPE) or silicone. For silicone materials, the KTW regulations still stand.
- Consists of three parts:
- A white-list of starting substances for compounding, assessed on toxicolo
- Test methods (migration testing procedures)
- Test values fowr limits
- The testing ensures that water must not be changed when passing by the seal, for example in terms of odor, flavor and color. It lso sets limits for organics and other substances migration.
