- Main application
The the following polyurethane elastomer system ‘U203-D57 polyurethane dark blue’ is approved for the use in applications that will come in contact with dry, and/or aqueous and/or fatty foodstuff. Tests have been performed in accordance with the US code for federal reg. 177-2600. Both n-Hexane and water extractables tests acc. to FDA CFR 177-2600 were performed by Akron Polymer Laboratory, Ohio, U.S.A. The tests determine if elastomer formulations can be used with dry, and/or wet, and/or oily foodstuffs. The results clearly show that the formulation passed the FDA requirements.
