Contact your Plexar sales and/or Equistar technical service representative for more information and specific recommendations for your application(s). Regulatory Status: PX3488 meets the requirements for the Food and Drug Administration regulation 21CFR 175.105 for adhesives. This regulation describes adhesives which may be safely used as components of articles intended for use in packaging, transporting or holding food in accordance with conditions outlined in that regulation. For an adhesive formulation to be used in compliance with Section 175.105, it must be used under conditions that prevent the material from becoming a component of food in more than insignificant, de minimis, amounts. Processing Techniques: A process melt temperature above 410°F (210°C) is recommended to ensure adhesion between adherents. This product is from the former Equistar product line. |
