Abstract: The present invention relates to processes for the preparation of polyurethane foams comprising a step wherein a chemical compound with a low particle size releases a chemical and/or physical blowing agent by decomposition, polyurethane foams prepared by such processes as well as compositions comprising at least one polyol and a chemical compound with a low particle size capable of releasing a chemical and/or physical blowing agent by thermally- and/or chemically-induced degradation and uses of such compositions.

Abstract: A composition which comprises 1,1,1,3,3-pentafluorobutane-(HFC-365mfc) and 1,1,3,3-pentafluoropropane (HFC-245fa) in a weight ratio HFC-365mfc/HFC-245fa of from 60:40 to 75:25.

Abstract: Compositions comprising phenolic biopolymers and a liquid medium comprising a halogenated polyol as well as their preparation and their use in the manufacture of polyurethane foams and premixes are disclosed.

Abstract: A composition which comprises 1,1,1,3,3-pentafluorobutane-(HFC-365mfc) and 1,1,3,3-pentafluoropropane (HFC-245fa) in a weight ratio HFC-365mfc/HFC-245fa of from 60:40 to 75:25.

Abstract: The invention relates to non-flammable compositions comprising fluorinated compounds selected from the group consisting of hydrofluoroalkanes, hydrofluoroalkenes, partially or perfluorinated aromatic compounds, hydrofluoroethers or fluoroketones, 1,2-dichloroethylene, especially trans-1,2-dichloroethylene, and a stabilizer. These non-flammable compositions which preferably contain 1,1,1,3,3-pentafluorobutane, can be used especially as solvents for cleaning and defluxing electronic components and for degreasing metals. The compositions further may comprise a propellant, e.g. 1,1,1,2-tetrafluoroethane. These compositions are especially suitable as flushing agent.

Abstract: Blowing-agent mixtures containing HFC-365mfc, HFC-227ea and one or both of 1,1,1,3,3-pentafluoropropane and 1,1,1,2-tetrafluoroethane are disclosed; as well as non-combustible polyether polyol and/or polyester polyol premixes for producing foamed products, in particular polyurethane foams.
