I-6650 ifilimu ye-Polyimide / i-polyaramide i-fiber paper flexible laminate (NHN) yi-three-layer flexible composite insulation paper apho icala ngalinye lefilimu ye-polyimide (H) lidibene nolunye uluhlu lwephepha le-polyaramide fiber (Nomex). Yeyona nto iphezulu yomgangatho wokugquma umbane, iklasi ye-thermal yi-H, ikwabizwa ngokuba yi-6650 NHN, i-H class insulation paper, i-H class insulation composite, njl.
