The importance of plastics
Plastics are a constant presence in everyday life. This is due to some advantages of these materials from which we can mention:
In developed countries, almost a third of plastics are used for consumer goods (eg packaging) and almost as much in construction. Other uses are for automobiles (up to 20%), the aerospace, furniture and toys industries.
In the world, almost 50 kg of plastic / person are produced annually, the production doubling every 10 years.
Plastics also have a wide use in the medical field with the introduction of polymer implants and other medical devices containing plastic as well as in the pharmaceutical industry (disposable syringes, capsules, packaging, etc.).
Plastics have solved some of the most important problems for cutting-edge fields of technology: in aerospace, electrical and electronic constructions (insulators of electrical conductors). Plastics have equaled the mechanical strength of metals, but they are much lighter and more resistant to atmospheric, aquatic and chemical agents and are just as transparent as glass, but unbreakable.
It is also resistant to moisture and bacteria.
There are high performance polymers that keep their mechanical properties within wide temperature limits (-50… + 500 ° C) and have very good chemical stability.
Nowadays, using plastic plastics, you can also make synthetic paper, namely banknotes.
It can therefore be concluded that plastics have become so common today that many activities would suffer if they did not exist.
- pleasant appearance;
- easy processing possibilities and relatively simple, productive equipment;
- wear resistance and high portability;
- accessible raw material bases;
- relatively low prices
