INTRODUCTION
Wide range of organic amorphous solids which are synthetic or semi-synthetic and are used for manufacturing of industrial products is plastic. Typically plastics are high molecular mass polymers, and may have other substances as its component in order of improving performance reduction in the costs. Plastic have its monomers which are generally either natural or synthetic organic compounds.
Plastic is a common word which should not be confused with technical adjective plastic which is applied to any material undergoing a permanent change of shape deformation of plastic when beyond a certain point it is strained.Please express your views of this topic Boron Family Characteristics by commenting on blog.
Types of plastics
Thermoplastics and thermosetting polymers.
1) On applying enough of heat thermoplastic will soften or melt polystyrene, polyethylene, polytetrafluoroethylene (PTFE) and polyvinyl chloride are examples of thermoplastics.
2) Thermosets are those plastics which can be melted and take shape once; they stay solid, after being solidified.
Natural gas and petroleum are raw material to make most of the plastics.

Toxicity of plastics
Due to relative chemical inertness and insolubility in water, generally the pure plastics have low toxicity in their finished state, without any harmful or ill effects they pass directly from the digestive system (excluding any obstruction or mechanical damage).
Variety of toxic additives is contained in plastic. Example to Brittle plastics plasticizers like adipates and phthalates are often added like polyvinyl chloride (PVC) to make them pliable enough so that they can be used in food packaging, teethers and toys, shower curtains tubing, and other items.
The monomers used in its manufacturing of plastic may be toxic while the plastic being manufactured may be toxic; and small amounts of those chemical may remain trapped in the product. The World Health Organization's International Agency for Research on Cancer (IARC) recognized the chemical as known human carcinogen, which are being used in making of PVC, vinyl chloride. On heating some polymers may decompose to give monomers or several toxic substances which are harmful to health and to environment.
The discarded plastic may cause lots of harmful effects when they decompose, as there are many areas where plastic is thrown the land over these areas have more toxicity in their soil.
