Microcellular polyurethane elastomer containing urea groups |
| abstract |
The invention relates to a microcellular PU elastomer with improved dynamic-mechanical characteristics, based on an isocyanate component consisting essentially of 4,4'-MDI and on other standard components. The proposed elastomer following tempering at temperatures of 100-120 ~C for 8-24 hours has a melting range of between 130 ~C as minimum lower limit and 230 ~C as minimum upper limit, as measured by differential scanning calorimetry (DSC) at a heating rate of 20 ~C/min and a urea content of 14-18 wt.%. Also disclosed are a process for producing such a microcellular PU elastomer with improved dynamic-mechanical characteristics and the use of said elastomers in the production of damping elements. |
