Plastics are organic substances formed by macrocells called polymers. These polymers are large groups of monomers linked by a chemical process called polymerization. Plastics provide the necessary balance of properties that can not be achieved with other materials such as: color, lightweight, soft touch and resistance to environmental and biological degradation.
In fact, plastic refers to a state of the material, but the material itself: synthetic polymers commonly called plastics are actually synthetic materials that can achieve the plastic state, ie when the material is viscous or fluid, and no resistance properties to mechanical stress. This state is reached when the material becomes solid plastic state usually by heating, and is ideal for different production processes and that this state is when the material can be handled in the forms that exist today. So the word plastic is a way to refer to synthetic materials capable of entering into a plastic state, but plastic is not necessarily the group of materials to which this word refers daily.
The properties and characteristics of most plastics (though not always fulfilled in certain special plastics) are these:
* Easy to work and shape,
* Have a low production cost,
* Possess low density,
* Tend to be waterproof,
* Good electrical insulators,
* Acceptable acoustic insulation,
* Good thermal insulation, but most can not withstand very high temperatures,
* Resistant to corrosion and many chemical factors;
* Some are not biodegradable or easily recyclable, and if they burn, are highly polluting.
