1C008 Non-fluorinated polymeric substances, as follows:
(a) (1) Bismaleimides;
(2) Aromatic polyamide-imides;
(3) Aromatic polyimides;
(4) Aromatic polyetherimides having a glass transition temperature (Tg) exceeding 513 K (2400C); (L.N. 95 of 2006)
Note:1C008(a) includes substances in liquid or solid "fusible" form, including resin, powder, pellet, film, sheet, tape and ribbon. (L.N. 226 of 2009)
For non-"fusible" aromatic polyimides in film, sheet, tape or ribbon form, see 1A003. (L.N. 226 of 2009)
(b) Thermoplastic liquid crystal copolymers having a heat distortion temperature exceeding 523 K (2500C) measured according to ISO 75-2(2004), method A, or national equivalents, with a load of 1.80 N/mm2 and composed of: (L.N. 95 of 2006; L.N. 254 of 2008)
(1) Any of the following:
(a) Phenylene, biphenylene or naphthalene; or
(b) Methyl, tertiary-butyl or phenyl substituted phenylene, biphenylene or naphthalene; and
(2) Any of the following acids:
(a) Terephthalic acid;
(b) 6-hydroxy-2 naphthoic acid; or
(c) 4-hydroxybenzoic acid;
(c) (Repealed L.N. 254 of 2008)
(d) Polyarylene ketones;
(e) Polyarylene sulphides, where the arylene group is biphenylene, triphenylene or combinations thereof;
(f) Polybiphenylenethersulphone having a glass transition temperature (Tg) exceeding 513 K (240oC); (L.N. 95 of 2006) Technical Note:
The glass transition temperature (Tg) for 1C008 materials is determined using the method described in ISO 11357-2 (1999) or national equivalents. (L.N. 95 of 2006)
