A plastics can be classified in many ways, but most commonly by their polymer backbone (polyvinyl chloride, polyethylene, polymethyl methacrylate).
We can found many uses of plastic.For example, Poly(vinyl chloride) (PVC) can be uses for Plumbing pipes and guttering, shower curtains, window frames, flooring.
For decades one of the great appeals of plastics has been their low price. Yet in recent years the cost of plastics has been rising dramatically. A major cause is the sharply rising cost of petroleum, the raw material that is chemically altered to form commercial plastics.
