Items:
a. Imides as follows:
a.1. Bismaleimides;
a.2. Aromatic polyamide-imides (PAI) having a 'glass transition temperature (Tg)' exceeding 563 K (290 °C);
a.3. Aromatic polyimides having a 'glass transition temperature (Tg)' exceeding 505 K (232 °C);
a.4. Aromatic polyetherimides having a 'glass transition temperature (Tg)' exceeding 563 K (290 °C);
Note:
1C008.a controls the substances in liquid or solid “fusible” form, including resin, powder, pellet, film, sheet, tape, or ribbon.
N.B.:
For non-“fusible” aromatic polyimides in film, sheet, tape, or ribbon form, see ECCN 1A003.
b. [Reserved]
c. [Reserved]
d. Polyarylene ketones;
e. Polyarylene sulfides, where the arylene group is biphenylene, triphenylene or combinations thereof;
f. Polybiphenylenethersulphone having a 'glass transition temperature (Tg)' exceeding 563 K (290 °C).
Technical Notes:
1. For the purposes of 1C008.a.2 thermoplastic materials, 1C008.a.4 materials, and 1C008.f materials, the 'glass transition temperature (Tg)' is determined using the method described in ISO 11357-2 (1999) or national equivalents.
2. For the purposes of 1C008.a.2 thermosetting materials and 1C008.a.3 materials, the 'glass transition temperature (Tg)' is determined using the 3-point bend method described in ASTM D 7028-07 or equivalent national standard.
The test is to be performed using a dry test specimen which has attained a minimum of 90% degree of cure as specified by ASTM E 2160-04 or equivalent national standard, and was cured using the combination of standard- and post-cure processes that yield the highest Tg.
