| 摘要 |
The invention relates to temperature-stable rigid foams which can be cold formed and have a density of 0 to 100 kg/m (according to DIN 53420), an elongation at break (according to DIN 53430) of 12 to 35%, a percentage of open cells (according to DIN ISO 4590-86) of 51% to 98% and a storage module of the foam (according to DIN EN ISO 6721 B:1996-12) in the temperature range of 60 DEG to 190 DEG C of, on average, greater or equal 0.1 MPa, and to composite materials produced with said foams. |
