摘要:
The present invention provides compositions comprising pentafluorobutane, a butane and optionally water. The present invention further provides for refrigerants, blowing agents, foam compositions, polyol premixes, closed-cell foams, sprayable compositions, and the like, comprising the present composition.
摘要:
An azeotrope-like mixture consisting essentially of chlorotrifluoropropene and at least one component selected from the group consisting of a C1 - C3 alcohol, a C5 - C6 hydrocarbon, a halogenated hydrocarbon, methylal, methyl acetone, water, nitromethane, and combinations thereof.
摘要:
The present invention provides methods of producing polyurethane and polyisocyanurate foams comprising reacting and foaming a mixture of ingredients that react to form a polyurethane or polyisocyanurate foam in the presence of a catalyst solution comprising a catalyst solvent and about 60 wt% or less, based on the total weight of the catalyst solution, of alkali metal salt. Also provided are foams produced via the methods of the present invention.
摘要:
Disclosed are low k-factor foams and methods of producing such foams. The methods comprise cooling high boiling blowing agent compounds to low temperatures and in introducing such cooled, high boiling blowing agents to the reaction mixture from which the foam is made.
