Abstract: The present invention relates to a molding composition, a process for the manufacturing of this molding composition, the molded parts obtainable from this molding composition as well as the use of the molding composition for the manufacturing of molded parts used in the automotive industry, for housings, latches, window winding systems, wiper systems, pulleys, sun roof systems, seat adjustments, levers, gears, claws, pivot housing, brackets, wiper arms or seat rails. The molding composition contains at least one polyoxymethylene having terminal OH-groups between 20 mmol/kg and 50 mmol/kg, at least one polyisocyante coupling agent, at least one reinforcing glass fiber that has been sized, and optionally at least one formaldehyde scavenger. The moldings produced from this 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.

Abstract: A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer and at least one tribological modifier. The tribological modifier may comprise an ultra-high molecular weight silicone having a kinematic viscosity of greater than 100,000 mm2 s−1. When tested against itself, the composition of the present disclosure exhibits an extremely low dynamic coefficient of friction and produces no discernible noise over a very broad temperature range, such as from −20° C. to 60° C.
