Plastic – is a chemical production, which consists of highly-molecular , long-chained polymers. There are 130 million tons produced in the world per year with annual increase 10%.
There are about 150 types of plastics. 30% of them are mixtures of different polymers. Different chemical additives are added into polymers, which are more than 20, and some of them are related as toxic materials, for gaining certain characteristics, better processing. These stabilizers protect plastics from high temperatures actions, sun light, colourants, which contain heavy metals (plumbum, mercury, cadmium, bromine, zink), lubricants, flame retarders – antipyrenes, antistatic agents etc.
