PLASTIC GLASS

Combination of a rubber-like plastic and glass has produced a new safety glass for motor cars. After being shattered it can be rolled like a rug without any of the glass becoming detached. A sheet of the glass was tested by having a heavy man jump on the middle of the pane. It shattered and sagged in the centre, but none of the splintered glass came free, and it continued to support the man, states an English paper. The secret of the new high-test safety glass lies in the new plastic, which has rubber-like stretching qualities and extremely high tensile strength. It was developed jointly in the course of six years’ research at the Mellon Institute, Pittsburgh, by the Carbide and Carbon Chemicals Corporation research department and a gz-oup of glass manufacturers. The safety glass is a laminated pane, a sandwich made up of two panes of glass with the synthetic rubber plastic between them. It adheres directly to the glass, and requires no cementing materials, as do other glass laminating plastics, and does not require edge sealing.
