Composite material.

摘要

A composite material comprises a first layer and a second layer, said layers being bonded together, wherein said first layer comprises 40 - 95 % by weight of an acrylic polymer formed from a monomer comprising 60 - 100 % methyl methacrylate and 0 - 40 % of a vinylic comonomer and 5 - 60 % of a copolymer wherein at least 10 % of the monomer residues are (optionally substituted) styrene and said second layer comprises a thermoplastic polymer. The material is particularly useful for forming sanitary articles, e.g. shower trays by thermoforming. A preferred second layer material is HIPS.
