Method of manufacturing a mold that is resistant to hypochlorite

A method of manufacturing a mold that is resistant to an aqueous solution containing hypochlorous acid and/or its salt,

• the method comprising molding a copolyamide molding compound comprising at least one amorphous or microcrystalline copolyamide (A) that contains the following monomers:
• (a) at least one cycloaliphatic diamine;
• (b) 0.25 to 3.0 mol % of at least one dimer fatty acid;
• (c) 12 to 49.75 mol % of at least one aromatic dicarboxylic acid selected from the group comprising isophthalic acid, terephthalic acid, and naphthalenedicarboxylic acid;
• and
• (d) 0 to 37.75 mol % of at least one aliphatic dicarboxylic acid;
• wherein the molar portion of isophthalic acid is at least equal to the molar portion of terephthalic acid;
• and
• wherein the monomers (b), (c), and optionally (d) add up to 50 mol % and the molar portions of all monomers contained in the copolyamide (A) add up to 100 mol %;
• wherein the mold is selected from the group consisting of components in swimming baths, whirlpools, heating systems, or in sauna or toilet, mixers, faucets, filter housings, water meters, water meter components, valves, valve components, distributors, cartridges, pumps, pump components inspection glasses, lines, and combinations thereof.
