A milestone has been reached in the tinplate manufacturing process: thyssenkrupp Rasselstein GmbH is now offering a new product with rasselstein® CFPA (Chromium-Free Passivation Alternative) now offers its customers 100 per cent chromium-free passivation on the tinplate surface.
The innovative product represents a Passivation alternative which effectively limits tin oxide growth during storage and therefore offers the same functionality as chromium-based passivations. Through the use of rasselstein® CFPA, customers of thyssenkrupp in Andernach can now invest in a Chromium-free future start.
Regulation (EC) No. 1907/2006 (also known as the REACH Regulation) regulates the use of chemicals throughout the EU. According to this Chromium (VI) compounds, previously used for the production of tinplate passivation are now only used for the production of deployed for a limited period become mandatory. For manufacturers of steel packaging, this means that they will no longer be able to obtain chrome-passivated tinplate produced in the EU.
