摘要： The invention relates to a moulding compound, comprising between 10 and 99.999 wt. % of at least one polyoxymethylene as component (A1) and between 0.001 and 10 wt. %, (in relation to the weight of the component (A1) contained in the moulding compound), of at least one zeolitic material with a pore diameter ranging between 0.3 and 0.5 nm, determined according to the DIN 66134 and DIN 66135 standards. The size of the particles of zeolitic material ranges between 3 and 7 µm, determined according to the ISO 13320 standard. The invention also relates to moulded bodies that are produced from said moulding compound.
