IMPROVED METHOD AND COMPOSITIONS FOR CABLE-BLOCKING

... 1284740 Method and compositions for cable blocking MINNESOTA MINING & MFG CO 4 Nov 1969 [5 Nov 1968] 54077/69 Heading H2C Cable blocks are formed in sheathed multiconductor pressurized cables by filling a short length of the cable with a liquid composition that self cures to form a solid polyurethane and allowing the curing to take place within the cable, the mixture exhibiting a controlled expansion. 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.
