The electronic industry is supported by the supply of raw materials from the petrochemical industry, without which it may grind to a halt.
The petrochemical industry is an aid to many of the end-use product industries. It is one of the major supplier of number of basic materials which is used by different other industries to manufacture their products. It has become one of the major sources of growth for the economy.
It is due to petrochemicals that the electronic industry has grown by leaps and bounds in the previous decade. The progress in the communication technology is the result of the improvements in the hardware devices such as radios, television sets, telephones, computers, CD players, DVD players, digital cameras, mobile phones, laptops, palmtops, etc. The circuitry of every electronic device is its most vital element. The circuitry mainly consists of micro processors, integrated circuits, printed circuits, and connectors - all derived from base materials of petrochemical products. Even the assembly and the housings are made out of styrenic plastics. Many of the cleansers used for cleaning the contact pins and lenses of the optical drives are based on petrochemical products.
CDs are made of a clear piece polycarbonate which is a type of a plastic made from benzene. The polycarbonate layer is imprinted with very minute - almost microscopic - protrusions which serve as exceedingly long spiral data tracks. The layer is covered with a thin aluminum covering and sprayed with a thin acrylic layer as protection. With the label printed on the acrylic layer, the CDs are packed into jewel boxes which are the transparent polystyrene plastic boxes in which CDs are sold. Then a thin acrylic layer is sprayed over the aluminum to protect it. The label is then printed onto the acrylic layer and the CD is placed into a polystyrene jewel box, the transparent, plastic boxes in which CDs are usually packaged.
