Carbodiimide-isocyanurate foams containing urethane linkages |
| 摘要 |
Carbodiimide-isocyanurate foams containing urethane linkages are prepared by mixing a polyisocyanate, a polyol and a catalyst system comprising an s-triazine compound and a catalyst which promotes urethane linkages. The resulting foams are characterized by low friability and good flame resistance.
