Essay On Role Of Polymers In Society

1003 Words5 Pages

Polymer is a long chains molecules which made up of many monomers all strung together by specify polymerization methods to form various types of products. There are two types of polymers in common which are natural polymeric materials such as wool, silk and synthetic polymers such as polyvinyl chloride (PVC), nylon and others. Moreover, different kinds of combination of monomers will produce distinct products with characterize properties such as tacticity, crystallinity, tensile strength, Young’s modulus of elasticity, glass transition temperature, melting point and others. Polymers are mainly contributed towards packaging industry, follow by building and construction, household domestic uses, automobiles, electrical and electronic, medical application and others. [1] In the society, enhancement of polymer technology has improved high quality of human life and healthy lifestyle in present day. Chemists keep on introducing modification of polymers that alter their physical and chemical properties for various societal needs by using sophisticated methods. Therefore, polymer has played an important role nowadays. [2]
Roles of polymers in society:

For example, polysaccharide is used for food packaging application, fast food containers used poly-L-lactic acid (PLLA), blend low density polyethylene (LDPE) is used for rubbish or groceries bags and other functions. The main advantage that polymer packaging is better than metal packaging is that metal would tend to be corroded and harmful in human body. [4] Besides, pharmaceutical products used polymer packaging as well. It can be either internal (tablet coating) or external (blister pack) packaging. [3] As a result, polymer packaging is now makes storage of foods and goods, medicine packaging are more convenient and efficient for the
