Reaction between isocyanate groups and active hydrogens is induced preferentially to reaction with a small amount of water in the mixture by means of a catalyst, for example a mono-organic-mercuric compound. When the mixture attains a viscosity of at least 50,000 centipoises, its composition is so chosen that reaction between the water and the isocyanate groups now takes place aided by a further catalyst, producing carbon dioxide sufficient to expand the mixture to 105-125% of its original size, so that the cable is firmly blocked. Materials used to form the block are disclosed.

SYNTACTIC POLYURETHANE ELASTOMERS HAVING DISTINCT MORPHOLOGY FOR USE IN SUBSEA PIPELINE INSULATION

Номер: CA0002928691A1
Принадлежит:

Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polyether polyol, a chain extender, a polyisocyanate and microspheres. The elastomer is characterized morphologically by the presence of small discrete morphological domains 0.1 to 3 µm in diameter, and the substantial absence of discrete morphological domains 5 to 30 µm in diameter. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.

Method of reducing odors of lipid-based polyols

Номер: US20140336347A1
Принадлежит: Green Urethanes Ltd

A method of reducing odors in lipid-based polyol. At least one lipid-based polyol is provided, and mixed with ricinoleic acid and/or a metal salt of ricinoleic acid. Isocyanate may be added, preferably toluene diisocyanate (TDI). The polyol, and the isocyanate when present, are reacted in the presence of the ricinoleic acid and/or a metal salt of ricinoleic acid which reduces or removes odors in the lipid-based polyol. When isocyanate is used, low, limiting levels are preferred, well below the level required to fully react with all of the polyol. Tin, zinc, sodium, and calcium ricinoleic acid metal salts are particularly preferred. Preferably the reaction takes place without added heat, at room temperature. The reaction may be performed in a chamber which is under at least a partial vacuum.
