LOW-MONOMER POLYURETHANE FOAMS |
摘要 |
A crosslinkable foamable composition with low content of monomeric isocyanates comprising a) 10 to 90 wt % of a prepolymer of polyester diols reacted with an excess of diisocyanates and subsequent removal of the excess monomeric diisocyanate, b) 90 to 10 wt % of a component based on polyether polyols which possesses at least one Si(OR)3 group or at least one NCO group, c) 0.1 to 30 wt % additives, d) and at least one blowing agent, wherein the polyester diols and the polyether diols have a molecular mass (MN) below 5000 g/mol and the mixture of a and b comprises a content of monomeric diisocyanates below 2 wt %. |
