Zusammenfassung:	FIELD: rubber industry. SUBSTANCE: invention, in particular, relates to fluororubber compounds and can be used for manufacturing, for example, sealing glands. Compound contains, wt parts: vinylidene fluoride/hexafluoropropylene copolymer (SKF-26) 66-68, low-molecular vinylidene fluoride/hexafluoropropylene copolymer 32-34, magnesium oxide 6-10, barium sulfate 26-30, calcium hydroxide 5-7, carbon black (TG-10) 20-26, low-molecular polyethylene 1-3, bisphenol A 0.8-1.0, catalyst 0.2-0.4. Catalyst is a compound of formula RR'R''R'''P+X-, in which R = R' = R" = R'" = N(Et)2, and X = Br-, BF-4. EFFECT: increased vulcanization rate and extended source of catalysts. 4 tbl, 2 ex _
