Abstract:
What is described is the use of a polyamide molding composition for the production of a stain-resistant article, the staining tendency (ST) of the article being at most 15. Here, the composition contains 30-100% by weight of a polyamide mixture, consisting of more than 50 and up to 98% by weight of at least one semi-aromatic polyamide comprising 2 to up to 50% by weight of amorphous and/or microcrystalline polyamides having a glass transition temperature of at least 100° C., based on: 20-100 mol % of at least one cycloaliphatic diamine; and 0-80 mol % of at least one other aliphatic and/or aromatic diamine; and also aromatic and/or aliphatic dicarboxylic acids comprising at least 6 carbon atoms. In addition, 0-70% by weight of fibrous additives (B1) and/or particulate additives (B2), 0-30% by weight of impact toughness modifier and/or polymers different from (A), 0-25% by weight of a flame retardant, and 0-3% by weight of additives may also be contained.
