Method for mixing blowing agents with polyurethane reagents for the production of polyurethane foam boards |
摘要 |
A method for manufacturing polyurethane and polyisocyanurate foams comprising the steps of charging at least one blowing agent and a polyol component to an in-line continuous mixer, wherein the at least one blowing agent and the polyol component are continuously charged in separate streams advanced at predetermined flow rates chosen to bring about a desired ratio of blowing agent to polyol component within the in-line continuous mixer.
