Transparent materials

Plastic is becoming more and more common in modern industry and the manufacture of everyday requirements since it is a perfect replacement for glass and has several advantages over glass, including light weight, exceptional durability, ease of moulding, and low cost. It has had an unusually quick development, particularly in the sectors of optical devices and the packaging business. However, as such plastic materials must have high levels of transparency (clearness), abrasion resistance, and impact resistance, a considerable deal of work is necessary in the areas of plastic ingredients and technology. In order to ensure that these glass substitute materials (hence referred to as transparent plastics) contain an exceptional surface polish and consequently fulfil the application criteria, equipment and moulds are used throughout the whole plastic injection moulding process. Polymethyl methacrylate (commonly known as acrylic or acrylic glass, abbr. PMMA), polycarbonate (abbr. PC), polyethylene terephthalate (abbr. PET), transparent nylon, acrylonitrile-styrene copolymer (abbr. AS), and polysulfone (abbr. PSF), among others, are currently the most widely used transparent plastic materials on the market. Now, in order to examine the qualities and the injection moulding procedure of transparent plastics, we will use these 3 materials as examples.
