Preparation of dimensionally stable one-component polyurethane foams using a two-compartment pressure pack containing an isocyanate-terminated prepolymer in the inner container and pressure medium in the outer container

摘要: A process for the preparation of a dimensionally stable one-component polyurethane foam from storage-stable mixture, under pressure, prepolymer based on polyols and containing isocyanate groups an organic blowing agent, with or without additives, by releasing pressure allowing mixture to react atmosphere cure, wherein foamable which contains 0.1 15% weight, weight groups, agent is introduced into inner container two-compartment pack, pack medium in outer container, discharged, when required, through dispensing device.
