| titleOfInvention |
Process for the preparation of rigid polyurethane foams with low heat-conductivity and their use |
| abstract |
The invention relates to a process for preparation of rigid polyurethane foams having low thermal conductivity by reacting n n a) organic and/or modified organic polyisocyanates with n b) at least one relatively high molecular weight compound having at least two reactive hydrogen atoms and optionally n c) low molecular weight chain extenders and/or crosslinking agents in the presence of n d) cyclopentane (d1) or mixtures (d2) which contain: n n d2i) cyclopentane and/or cyclohexane and n d2ii) at least one compound which is homogeneously miscible with cyclopentane and/or cyclohexane and preferably has a boiling point below 35 DEG C, selected from the group consisting of the alkanes, cycloalkanes having not more than 4 carbon atoms, dialkyl ethers, cycloalkylene ethers and fluoroalkanes,n optionally in conjunction with water, as blowing agents (d), n n e) catalysts and optionally n f) auxiliaries and/or additives. n n<??>The rigid polyurethane foams are used in the refrigerator industry and as insulating material in heating and composite elements. |
