Carbon black-filled polyurethane rigid foam with improved aged k-factor |
| abstract |
A rigid, closed-cell polymer foam is described comprising the reaction product of a polyisocyanate and a compound reacting with isocyanates in the presence of a) a foaming agent, b) of at least about 2% by weight of carbon black relative to the weight of the polymer contained in the foam, and c) of a capped polyoxyalkylene compound which facilitates a uniform dispersion of the carbon black in the foam, so that the aging factor k of this foam is lower than that of the corresponding foam devoid of charge. |
