| 摘要 |
A thermal insulation material, and a method for its manufacture, are disclosed. The material is suited to underwater use. It comprises a matrix (20) of cured polymer material, most preferably polyurethane, in which are embedded insulation bodies (10) each comprising a core (12) of foamed material and an outer structural plastics layer (10). The materials and the manufacturing conditions are chosen such that temperatures within the low density bodies during manufacture are not sufficient to destroy the foamed cores. The result is a material with excellent thermal insulation properties. |
