Kann Bornitrid auch in der Lebensmittelindustrie eingesetzt werden?

Yes, boron nitride can be used in the food industry. Its applications include, in particular:

Lubricants for food processing: Certain boron nitride powders from Henze BNP (such as HeBoFill® LL-SP 010 and HeBoFill® LL-SP 050) are NSF-certified (Category HX-1). These powders may be used as additives in lubricants where incidental contact with food may occur. This allows their use directly in and around food processing production facilities. In addition, boron nitride lubricants have received the necessary FDA and EU approvals for food contact.
Food packaging: Boron nitride is also used as a functional filler in polyolefin blown films, which are used in food applications.
