摘要 |
A spacer is coiled about a drawn, seamless copper tube, and a metal foil or metallized paper ribbon is folded around the coiled spacer. A blend for foaming is injected into the unoccupied space between the folded foil or ribbon and the inner tube, to generate a cyanurate-modified polyurethane foam network in which phosphorous or halogen molecules are embedded by chemical bond. A flame-resistant ribbon is folded about the metal tube. The resulting product and further details of the process are described. |
