A plastic can be defined as an artificial substance that is made from organic polymers. Plastic can be extruded in various shapes like windows frames, sashes etc. Plastic facts cover up many topics like the advantages of plastics, disadvantages of plastics, chemical composition of plastic etc. Carbon, hydrogen, oxygen, and nitrogen are the chemicals found in plastics. Uses and Advantages of plastics
- Aeronautics :- In the field of aeronautics, plastics are now being preferred over other elements, for the use in spaceships. This is so because plastics and its derivatives produce minute secondary radiation as compared to the heavier metals like lead, aluminum etc.. Hence plastics are used in the ablative shields for the return of space shuttles.
- Building and Construction :- Plastics have the cutting edge corrosion resistance property. This makes plastic very popular to be uses in various pipes and valves. Plastics are lighter, cheaper and easy to install.
- Decoration :- The properties of plastics like durability, attractiveness, and easy handling make them a astounding decorative items.
- Electronics :- The insulating and thermal properties of the plastics, make them ideal for the use in various electronic devices.
- Packaging :- Plastics are very versatile, due to what plastics are used for various packaging purposes. Plastic can be termed as a rigid material.
Disadvantages of plastics
- Flammable :- Cellulose nitrate is considered to be the original plastic. It was highly flammable. Latest plastic products use fire retardants but they, to some extent, only increase the time taken to catch fire. A plastic when burned, produces thick and health hazard smoke containing the toxic carbon mono-oxide in abundance. Once the plastic goes in flame, it burns faster and hotter than the other natural substances.
- Decomposition :- Decomposition of plastic can be defined as the breaking of plastics into different smaller or simpler compounds. Plastics are made by the long-chained molecules and hence decomposition of plastics can be a negative factor. While remolding the negativity, decomposition can increase to a high extent. The decomposition of plastics results in the emission of toxic chemicals like carbon mono-oxide, benzene etc.
Some other facts
- The first cellulose nitrate plastic was developed in 1846, by Christian Friedrich Schonbein. He was from Germany.
- As compared to the seven trucks required to deliver paper grocery bags, only one truck does the trick to carry the same number of plastic grocery bags.
- Plastic lumber, made with recycled plastic holds nails and screws better than wood & is virtually maintenance free.
