Transparency applications of Polycarbonates

POLYCARBONATE can now be considered among the select group of aircraft transparent plastics and it has several key properties that make it attractive to the aircraft designer particularly because of its impact resistance and good strength at elevated temperatures, raw material suppliers and other manufacturers have struggled to overcome the chemical and physical shortcomings of this material. Optics have been improved both in a ‘cleaning‐up’ of raw resin and the extrusion proces‐sing, and also through optical flattening by pressure polishing of the surfaces. By this latter means, thicknesses greater than the normal sheet extrusion capacity can be built up from thinner gauges by simply welding them together without the use of adhesives or solvents. To summarise: Major Advantages:
