What are the greatest advantages plastics may give the world?
THE WONDERLAND OF PIASTICS
1. Plastics or synthetic resins as they are sometimes called, are entirely the product of modern chemistry and are like no other substances found on the earth or in the sea. The discovery of plastics has at last opened the road which will lead man to victory over nature and make him independent of nature's products.
2. But what is a plastics and why are the chemists so enthusiastic over them? Synthetic plastics are man-мейд substances which not only change their shape when moulded under great heat and pressure, but change their chemical state as well.
3. They are light, hard and amber-like, being produced by mixing together a number of gases and liquids. Asynthetic-orman-мейд-product must necessarily be both better and cheaper in order to justify its manufacture at all. This is essentially true of the various plastics when compared to the material they are to replace.
4. As for plastics themselves, there are two kinds those which are affected by heat and those which are not, or cast plastics and moulded plastics. Cast plastics are manufactured as liquid resins and are then cast in the desired forms. Cast resins can be coloured before being poured. The resulting plastics can be produced in all sorts of colours, more than three hundred different shades and colours, being now available in the cast plastics.
5. Moulded plastics are usually mixed with fillers to strengthen the finished material and give it certain characteristics. The mixed materials are subjected to tremendous pressure and temperature until they flow and fill the mould. Since the great heat used destroys dyes, moulded plastics can be in only a few shades, usually black.
6. The greatest advantages which plastics are expected to give the world is that they will make the people no longer dependent upon nature for their materials. Chemists look upon the invention of plastics as marking the beginning of the time when they will be able to control more fully the atoms and molecules which compose all material things.
