Leverkusen - Bayer Chemicals, a division of Bayer AG, has increased the production capacity for its BlankophorŪ fluorescent whitening agents at the Leverkusen site by over ten percent compared to last year. According to the production manager, Dr. Klaus-Dieter Schultz, this was made possible by optimizing the production process - including the laboratory workflows - in the FWA plant, which was built in 1998. 95 percent of the FWAs in the comprehensive BlankophorŪ range are used in the paper industry for internal or surface application or for adding to coating paints. The inclusion of FWAs results in better contrast when printing graphic papers and more brilliant colors. FWAs absorb light from the UV range, which is invisible to the human eye, and emit blue light. The reflectance can even exceed 100 percent. This physical process makes the paper look whiter. So these advertising slogans that promise "dazzling white" or "whiter than white" effects are not as ridiculous as they are often made out to be. Bayer's involvement with FWAs dates back to 1941, when the Bayer chemists Otto Bayer and Siegfried Petersen and the Agfa research scientist Bruno Wendt developed the first FWAs to be patented in Bayer's Central Scientific Laboratory. Since then, the company has continued to optimize and expand its successful range of products. Bayer Chemicals developed some new FWAs again last year and introduced them onto the market. Five new tetrasulfo types were added to the BlankophorŪ range - three for brightening coatings and two for use in the size/film press. Bayer Chemicals offers one of the most comprehensive product portfolios for the paper industry. An overview of the different ranges can be found on the Internet under www.solutionsforpaper.com. |
