摘要： A mold is described for the molding of substantially isotropic isocyanate-based polymer foam buns. The mold is a box mold which has sidewalls of which at least one pair disposed in parallel relationship is adapted to move outwardly when subjected to pressure exerted by the expanding foam during the molding operation. The outward movement of the sidewalls is controlled by stops provided on the periphery of the mold floor, said sidewalls being free to slide over the surface of the floor. The lid of the mold is supported in sliding engagement with the upper edges of the sidewalls. The mold and the process of fabricating foam buns therewith is particularly suitable for use in situations (e.g. operation in the field) in which it is not possible or practicable to employ continuous bunstock machines. The mold is relatively inexpensive and readily dismantled for transportation to a fabrication site.

摘要： Rebond polyurethane foams can be prepared by coating shredded polyurethane foam with a prepolymer binder formulation which includes toluene diisocyanate distillation bottoms, compressing the binder coated foam, and the curing the binder with steam. The toluene diisocyanate distillation bottoms can be used in place of more expensive prepolymer formulation components such as toluene diisocyanate or methylene diphenyldiisocyanate. The toluene diisocyanate distillation bottoms can also improve elongation and tear resistance properties of the resultant rebond foams prepared therewith.

摘要： A method of treating toluene diisocyanate distillation residues comprising reacting the residues with at least about 0.5 equivalents, based on hydrolyzable chloride concentration of the residues, of an epoxy compound at a temperature of from about 155 to about 220.degree. C. to produce a treated distillation residue having a hydrolyzable chloride level of less than about 800 parts per million (ppm) is taught. The product of the method is useful, for instance, in producing rigid foams with low K Factors.
