摘要:
The invention relates to certain non-flammable compositions containing 1,1,1,3,3-pentafluorobutane (R365mfc), 1,2-dichloroethylene, ethoxynonafluorobutane (HFE-7200), and a linear C1 to C4 alcohol as well as to mixtures containing these compositions and to the use of these non-flammable compositions or these mixtures, especially as precision cleaning agents for solid surfaces and for flushing, especially of refrigeration systems.
摘要:
The present invention concerns the field of fluorinated hydrocarbons and relates to novel compositions containing fluorinated hydrocarbons, secondary butanol and optionally DMSO. These novel compositions are particularly advantageous for defluxing electronic boards in particular for defluxing electronic boards containing “no clean' solder fluxes.
摘要:
The present invention relates to a pentafluorobutane composition which comprises 100 parts by weight of 1,1,1,3,3-pentafluorobutane and 0.01 - 10 parts by weight of at least one stabilizer selected among the following (A) to (D): (A) 3,4-epoxycyclohexenylmethyl 3',4'-epoxycyclohexenecarboxylate; (B) ε-caprolactone-modified 3,4-epoxycyclohexylmethyl 3',4'-epoxycyclohexanecarboxylate; (C) vinylcyclohexene monoxide; and (D) 1,2:8,9-diepoxylimonene.
摘要:
According to the present invention, a composition comprising 1,3,3,3-tetrafluoropropene (HFO-1234ze) finds use as a blowing agent. The invention also relates to foamable compositions, pre-blended compositions, foams and methods of forming foams, containing and using HFO-1234ze.
摘要:
The invention relates to a composition comprising trans 1,2-dichloroethylene, more particularly, a non-flammable composition (no flashpoint), comprising trans 1,2-dichloroethylene and pentafluoropropane and use thereof.
