Abstract

1431154 Making matt surfaces ROHM GmbH 21 March 1974 [27 March 1973] 12660/74 Heading B6J [Also in Division B5] Thermoplastic sheet 6 is given a matt surface by being heated to above its glass transition temperature, placed in contact with a flexible foam 5 or 5a, and pressed against it, then cooled in contact with the foam. The sheet 6 may be of polymethyl methacrylate and the foam of foam rubber, entrapped foam silicone rubber or polyurethane. Application of a matt surface may be combined with moulding of the sheet 5, or with its passage between rollers.
