The word 'plastics' is a general term for artificially made substances which can be moulded and squeeezed and pressed into various shapes, generally after they have been heated. When they cool, they set in the required shape. Different plastics have different properties. Some are hard when set, others flexible. Some can't be softened with heat, others can (these are known as thermoplastics).
