Why Is Plastic Important?
The versatility of plastic materials comes from the ability to mold, laminate or shape them, and to tailor them physically and chemically. There is a plastic suitable for almost any application. Plastics do not corrode, though they can degrade in UV (a component of sunlight) and can be affected by solvents — for example, PVC plastic is soluble in acetone.
We are getting wiser, though, and now many plastics can be chemically, mechanically, or thermally recycled
