26 2 Application of silicones in Denmark 2.1 Raw materials production, import and export The statistics from Statistics Denmark (Danmarks Statistik) hold information on one commodity only for which it is explicitly stated that the commodity includes siloxanes or silicones. Import, export and production of unprocessed silicones for the years 1998- 2001 are shown in Table 2.1. The main part of unprocessed silicones is sealants packed in Denmark. As silixanes only account for a part of the sealants, the amount of silicones will be less than indicated. Table 2.1 Import,export and production of unprocessed silicones (Statistics Denmark 1988-2002) Year Import tonnes Export tonnes Produktion in DK tonnes Supply * tonnes 1998 2,445 875 11 1,581 1999 1,998 526.6 14 1,486 2000 1,783 483.2 11.5 1,311 2001 1,765 577.6 12.4 1,200 * supply = import + production - export 2.2 Fields of application 2.2.1 Data from the Danish Product Register A list of siloxanes and siloxane-containing substances registered in PROBAS, the database of the Danish Product Register was retrieved. The retrieval comprises substances with chemical names including the text strings 'silox', 'silicone', 'methicon' or 'silsesquio'. For each substance the total content of the substance in imported and exported products as well as in products produced in Denmark by application areas and branch was retrieved. The application areas registered in PROBAS are, however, not fully identical with the application areas defined in this study, and the data from PROBAS is only to some extent immediately applicable. In addition, only a part of the siloxanes in products is registered. Companies only have the obligation to submit information on the turnover of products to PROBAS, if the products contain substances classified dangerous (Bek. 439, 2002). Siloxanes are generally not classified dangerous. If the products contain dangerous substances, however, all constituents of the products are registered. The retrieval thus includes siloxanes in products in which other substances are classified dangerous. In total 175 siloxanes or siloxanes-containing substances are registered as used in Denmark. The substances are listed in Annex 3. The total import, produc-
tion and export of siloxanes registered in the Danish Product Register by application area is shown in Table 2.2. The total content of siloxanes in registered, imported products is 1,269-1,483 t in 78,000-90,500 t of products. The total content of registered products produced in Denmark is 162-1,143 t in 45,000-293,000 t of products. The data demonstrate the widespread use of siloxanes at low concentration in a very large product volume. It should be noted that the supply calculated as import + production - export is only indicative. Siloxanes imported for production often will be registered in two different categories for import and production, respectively, e.g. imported emollients may be used for production of paints.

One substance is excluded for reasons of confidentiality. For most of the substances a large number of application areas and branches are registered, and the retrieval demonstrates that many of the siloxanes are used for a large range of different applications. 27
