Abstract: A thermoplastic molding composition comprising (A) 15 to 45 wt.-% graft copolymer (A) obtained by emulsion polymerization of styrene and acrylonitrile in presence of an agglomerated butadiene rubber latex (A1) with D50 of 150 to 800 nm; (B) 40 to 75 wt.-% copolymer (B) of styrene and acrylonitrile having a weight ratio of 80:20 to 65:35 and Mw of 150,000 to 300,000 g/mol, (C) 2.0 to 5.0 wt.-% elastomeric block copolymer (C) made from 15 to 65 wt.-% diene, and 35 to 85% by weight vinylaromatic monomer; (D) 2.0 to 5.0 wt.-% titanium dioxide pigment D comprising at least 95 wt.-% titanium dioxide and 1.7 to 3.3 wt.-% alumina; and (E) 0 to 7.0 wt.-% of at least one additive/processing aid (E) different from (D); having a high chemical resistance, high color and thermal stability and low tendency to delamination. This can be used for sheet extrusion and thermoforming, in particular as inner liner for a cooling apparatus.
