Perspex glazing

During this period, the ICI laboratories were also making their other great contribution to the range of plastics materials—the product which they marketed as Perspex, poly(methyl methacrylate). As a result of work by two of their chemists, R. Hill and J. W. C. Crawford, it was found that a rigid transparent thermoplastics material could be produced at a commercially feasible cost. The material became invaluable during World War II for aircraft glazing and to a lesser extent in the manufacture of dentures. Today poly(methyl methacrylate) is...

Acrylic has also been used in the production of polybem. Sometimes called Perspex , it is a bright, glossy polymer, which has been used for glazing. It has a relatively low chemical resistance.

The other development by ICI laboratories which made a vital wartime contribution was poly (methyl methacrylate), widely known as acrylic, Perspex or Plexiglas. First produced commercially in the UK in 1934, its rigidity, transparency and shatter-resistant properties were soon in high demand for glazing, aircraft canopies and protective screens because acrylics provided a lower density, weather-resistant alternative to glass (Figure 2.10). Production of poly (methyl methacrylate) increased 1200 per cent during the period 1940-43 due to the escalation in production of aircraft (Kline, 1944).
