Water-tree-resistant electric insulator compositions

Water-tree-resistant electric insulator compositions. 9002-88-4 are also occured in this study. (Dainichi Nippon Cables, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59121704 A2 13 Jul 1984 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: H01B003-30. APPLICATION: JP 82-230064 28 Dec 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 38 The compns. contain elec. insulating polymer and I (X = N, O, S; R = H, C￡10 alkyl, aryl). Thus, Yukalon ZF-30 (low-d. polyethylene) [9002-88-4] 100, dicumyl peroxide 2, Cu powder (325 mesh) 0.1, and I (R = H, X = S) [7405-23-4] 0.5 part were roll-blended at 115° and press-cured at 170° for 45 min to give a 3 mm sheet specimen which was then coated on both sides with a semiconductive electrode material and subjected to treeing test using 22 mmol/L aq. CuSO4 at 10 kV a.c. (1200 Hz) for 240 h to give av. length of tree (initiated from Cu powder) 86 mm, compared with 148 for a control not contg. I. .
