Thermoplastic plastics moulding matter, process of manufacture and moulding made therefrom

摘要

After removing coarse fragments of glass and metal splinters from the grinding stock from motor vehicle rear light and indicator light units, it is possible to obtain from said stock a high-grade moulding composition comprising 50-65% PMMA, 25-40% ABS and 1-20% PC for the production of new rear-light and indicator-light housings. The constituents which melt at over 250@C and are longer than 0.2mm, if desired longer than 0.04mm, are separated off by melt filtration, thereby considerably improving the service properties.
