177.1595 Polyetherimide resin


  The polyetherimide resin identified in this section may be safely used as an article or component of an article intended for use in contact with food, subject to the provisions of this section.

  (a Identity. For the purpose of this section, the polyetherimide resin is 1,3-isobenzofurandione, 5,5[?-methyl-ethylidene)bis?,1-phenyleneoxy)] bis-polymer with 1,3-benzenediamine (CAS Reg. No. 61128-46-9? and is derived from the condensation reaction of m -phenylenediamine and bisphenol A-dianhydride.

  (b Optional adjuvants. The basic polymer identified in paragraph (a of this section may contain optional adjuvant substances required in the production of basic resins or finished food-contact articles. The optional adjuvant substances required in the production of the basic polymer may include substances permitted for such use by applicable regulations as set forth in part 174 of this chapter.

  (c Specifications and extractives limitations ? Specifications. Polyetherimide resin identified in paragraph (a of this section shall have an intrinsic viscosity in chloroform at 25 C ?7 F of not less than 0.35 deciliter per gram as determined by a method titled Intrinsic Viscosity of ULTEM Polyetherimide Using Chloroform as the Solvent, which is incorporated by reference. Copies are available from the Center for Food Safety and Applied Nutrition (HFS-200? Food and Drug Administration, 5100 Paint Branch Pkwy., College Park, MD 20740, or available for inspection at the National Archives and Records Administration (NARA? For information on the availability of this material at NARA, call 202-741-6030, or go to:http://www.archives.gov/federal_register/code_of_federal_regulations/ibr_locations.html.

  ? Extractive limitations. Extractive limitations are applicable to the basic polyetherimide resin in the form of molded discs of thickness 0.16 centimeter ?.063 inch? The resin discs when extracted with distilled water at 121 C ?50 F for 2 hours yield total nonvolatile extractives of not more than 12.3 micrograms per square centimeter.
