Catalytically active polyols cut emissions. (RIM/Urethanes).A new line of catalytically active polyols is said to dramatically reduce amine amine (əmēn`, ăm`ēn): see under amino group. amine Any of a class of nitrogen-containing organic compounds derived, either in principle or in practice, from ammonia (NH3). emissions from polyurethane foam Noun 1. polyurethane foam - a foam made by adding water to polyurethane plastics polyfoam polyurethan, polyurethane - any of various polymers containing the urethane radical; a wide variety of synthetic forms are made and used as adhesives or plastics or . Voranol Voractiv polyols from Dow Plastics, Midland, Mich., graft graft, in surgery: see transplantation, medical. graft In horticulture, the act of placing a portion of one plant (called a bud or scion) into or on a stem, root, or branch of another (called the stock) in such a way that a union forms and the the catalytic activity into the polyol, saving processors a formulating step. The amount of amine catalyst needed for foaming is significantly reduced. The process is said to simplify production of automotive foams as well as carpet cushioning, packaging, bedding, and furnishings furnishings the extra type or quantity of hair on the head, tail, ears or legs, specified for a particular breed. For example, the feathers in setters, the beard in Bearded collies, the eyebrows in Schnauzers. . Dow says PUR foam manufacturers can expect to get more uniform and consistent foams. They can also expect better compression-set properties, including humid-aging resistance, Dow says. *77* |
