Abstract:
A housing for security equipment, selected from the class consisting of housings of alarm systems and parts thereof, and housings which accept sensors for detecting, or transmitters for sending, optical signals, acoustic signals, movement signals or thermal signals or also any part thereof made from a thermoplastic molding composition differing from ABS and comprising, based on a total of 100% by weight of amounts of components A and B, and, if desired, C and/or D,a: as component A, which is a graft copolymer, from 1 to 99% by weight of a particulate emulsion polymer with a glass transition temperature of below 0.degree. C. and with a median particle size of from 50 to 1000 nm,a1: from 1 to 99% by weight, of a particulate graft base A1 with a glass transition temperature below 0.degree. C.,a2: from 1 to 99% by weight, of a graft A2 made from these monomers, based on A2,a21: as component A21, from 40 to 100% by weight of units of a vinylaromatic monomer, anda22: as component A22, up to 60% by weight of units of an ethylenically unsaturated monomer where the graft A2 is composed of at least one graft shell,b: as component B, from 1 to 99% by weight of at least one amorphous or partly crystalline polymer,c: as component C, from 0 to 50% by weight of polycarbonates, andd: as component D, from 0 to 50% by weight of fibrous or particulate fillers or mixtures of these.
