Abstract

The present invention relates to a molding composition, a process for manufacturing the molding composition, and molded parts obtainable from the molding composition. The molding composition can contain at least one polyoxymethylene having terminal OH-groups, at least one polyisocyanate coupling agent, at least one reinforcing fiber, and at least one formaldehyde scavenger. The moldings produced from the molding composition are distinguished by their improved mechanical properties while having low formaldehyde emissions and excellent tensile strength while having a good flex fatigue and creep performance.
