Beschreibung
Zusammenfassung:	FIELD: sealing materials. ^ SUBSTANCE: sealing composition comprising fluorosiloxane rubber, mineral filler, tin diethylcaprylate, and polyethylhydrosiloxane is characterized by that above fluorosiloxane rubber is, more specifically, polydimethylmethyltrifluoropropylsiloxane rubber and composition additionally contains calcium stearate and iron oxide with following amounts of components, wt parts: rubber 100, mineral filler 90-300, tin diethylcaprylate 1-4. polyethylhydrosiloxane 4-8, calcium stearate 0.2-0.5, and iron oxide 0.5-1. ^ EFFECT: increased resistance to heat and fuel and reduced coefficient of linear thermal dilatation allowing composition to be used as intrajoint hermetic. ^ 3 cl, 1 tbl, 4 ex
