FOAM-FORMING MIXTURES WITH DECREASED DECOMPOSITION OF HYDROHALO-CARBON BLOWING AGENTS |
| 摘要 |
A polyisocyanate having an acid value of at least 0.01% HCl is used to produce polyisocyanate, polyisocyanurate and polyurethane urea foams with an HCFC blowing agent. The use of such a polyisocyanate is advantageous because the polyisocyanate does not cause significant decomposition of the HCFC blowing agent.
