Plastics are derived from organic products. The materials used in the production of plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil.Crude oil is a complex mixture of thousands of compounds. To become useful, it must be processed.he materials used in the production of plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil.
The basic binding materials in plastic are resins, which undergoes polymerization and condensation reactions during the preparation of plastic. There are two types of plastics, thermoplastics and thermoset plastics. Examples of thermoplastics include polythene (PE), polypropylene (PP), polyvinyl chloride (PVC), polytyrene (PS), nylons, and polytetrofluoro ethylene (PTFE or Teflon). Examples of thermoset plastics include phenolic resins, amino resins, polyester resins, silicon resins, epoxy resins, and polyurethanes. This handbook discusses the types, properties, uses, and advantages of thermoset plastics.
