PURPOSE: Massagers and housing thereof has stability of the dental pulp, yellowing resistance, and excellent chemical resistance. CONSTITUTION: Thermoplastic molding materials which are different from ABS and which, in relation to the sum of the quantities of components A and B and optionally C and/or D resulting in a total of 100 wt %, contain a) 1-99 wt %, preferably 15-60 wt %, in particular 25-50 wt % of a particulate emulsion polymer with a glass transition temperature of less than 0°C and a mean particle size of 50-1000 nm, preferably 50-500 nm as component A, b) 1-99 wt %, preferably 40-85 wt %, in particular 50-75 wt % of at least one amorphous or semi-crystalline polymer as component B, c) 0-50 wt % polycarbonate as component C and d) 0-50 wt % fibre or particulate filling materials or their mixtures as component D. The materials are used for producing massagers and housing thereof.
