PLASTICS


Definition of Plastic:

A plastic (from the Greek "plastikos," meaning moldable) can be broadly defined as any non-metallic synthetic material made from a wide range of organic polymers such as polyethylene, PVC, nylon, etc., that can be moulded into shape while soft and then set into a rigid or slightly elastic form.

-- Most plastics are of organic nature composed of hydrogen, oxygen, carbon and nitrogen.
-- The synthetic plastic development dates from 1900 when Dr. Beekland announced the production of Phenol formaldehyde (Bakelite). Since then several plastics have been developed.
-- The basic raw materials used in the manufacturing of plastic come from natural resources such as oil, gas and coal (fossil fuels).
