PLASTIC MATERIAL

             PLASTIC   MATERIAL    Plastic   are a wide range of synthetic  or semi-synthetic materials that use polymer s as a main ingredient. Their plasticity  makes it possible for plastics to be moulded , extruded  or pressed  into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemical  like natural gas  or petroleum  however, recent industrial methods use variants made from renewable materials, such as corn  or cotton  derivatives. In developed economies, about a third of plastic is used in packaging and roughly the same in buildings in applications such as piping , plumbing  or vinyl   sid...
