摘要:
The invention relates to a process for the preparation of cellular or non-cellular polyurethane-polyurea molded articles. The new process involves the use of urethane and isocyanurate group modified 2,4- and/or 2,6-toluene diisocyanate mixtures as the polyisocyanate component to improve the flowability of the reaction mixture without adversely affecting the mechanical properties of the resulting molded articles.
