The invention relates to composites VS composed of at least two plastic layers A and C , suitable for the production of articles which come into contact with water on a surface which has temperatures between 0 and 90 degrees C, the layer A coming into contact with water a thermoplastic impact-resistant polymethyl methacrylate plastic SP and layer C are constructed from an impact-resistant plastic, with the features that the impact-resistant polymethyl methacrylate plastic SP forming layer A has a Vicat softening temperature VET according to ISO 306, method B, of at least 95 degrees C. and has a notched impact strength SZ according to ISO 180 1A of at least 3.0 KJm⁻², and that layer C consists of an impact-resistant acrylonitrile-styrene copolymer VP. In a preferred embodiment of the invention, a further layer B made of a thermoplastic polymethyl methacrylate plastic P is arranged between layer A and layer C. |
