| titleOfInvention |
Syntactic rigid pur/pir foam boardstock |
| abstract |
The present invention relates to the use of hollow microspheres filled with a hydrocarbon, to introduce uniform cell geometries in syntactic foams having a bimodal cell structure. The rigid foam product includes from 40 to 60 percent by weight of the hollow microspheres, the microspheres having average diameters ranging from 80 to 140 microns. The microspheres are encapsulated from 60 to 40 percent by weight of a closed cell polyurethane foam, the cells of the foam having average diameters from 0.01 to 40 microns. |
