PREPARATION OF LOW FRIABILITY RIGID POLYURETHANE FOAM |
| 摘要 |
<p>An improvement is disclosed in the preparation of rigid polyurethane foams which have relatively high surface friability. The improvement resides in the use of a select group of supplemental polyether polyols having 2-3 hydroxy groups in order to reduce the friability of the resulting foam.</p> |
