The present invention provides blowing compositions for preparing foamed or expanded products of thermoplastics. Each of the blowing compositions comprises a combination of two of halogenated hydrocarbons.

Blowing compositions

Solvent composition comprising a chloropentafluoropropane and a

The invention provides a dehydrating agent comprising at least one of fluorine-containing alcohols; a dehydrating agent comprising at least one of fluorine-containing alcohols and water; and a method of dehydrating and drying an article having a surface moistened with residual water, the method comprising immersing the article in a dehydrating agent comprising at least one of fluorine-containing alcohols or comprising at least one of fluorine-containing alcohols and water, and drying the article after the immersion.

Fluorine-containing alcohol-based dehydrating agent and method of drying

Incombustible azeotropic like solvent compositions comprising 87 to 92 parts by weight of 1,1,2-trichloro-1,2,2-trifluoroethane and 8 to 13 parts by weight of hydrocarbons, said hydrocarbons have a boiling point of 49.degree. to 58.degree. C.

Incombustible azeotropic like solvent compositions

An azeotropic solvent composition which comprises an azeotropic mixture of 77% by weight of Flon-113 and 23% by weight of cyclopentane. The composition can decrease the amount of 1,1,2-trichloro-1,2,2-trifluoroethane excellent in power for dissolving fats and oil, grease, and particularly, waxes used for temporarily fixing silicon wafers, quartz, ceramics without erosion of materials made of plastics and rubbers, and it is easy to control the liquid composition and easy to recover and reuse the composition.
