advantages of using polythene

. Hence it is used in insulation of electric wires, manufacturing of squeeze bottles, toys and flexible pipes. When polymerization of ethylene is carried out in the presence of a catalyst at about 330 to 350 K, at atmospheric pressure, the polymer obtained has a linear structure and is ca..

Polyethylene or Polythene - Polythene is formed by the addition polymerization of multiple monomers of ethylene or ethene. When liquid ethylene is polymerized at high temperature and pressure, a resin of polyethylene is obtained. It can be melted spun or moulded as desired. Note..

It can be used to measure temperature accurately because of its electrical nature and a wide range of temperature difference(0.001K - 2000K) It absorbs a very small amount of heat from the object and therefore does not change the temperature to be measured. As the thermal capacity..

In the manufacture of ethyl alcohol and ethylene glycol which are used as important starting materials in the manufacture of synthetic fibres. Manufacture of plastics like polythene. In artificial ripening of fruits like bananas, apples and oranges..

The offsprings are genetically identical and therefore advantageous traits can be preserved. Only one parent is required which eliminates the need for special mechanisms such as pollination, etc. It is faster. For example, bacteria can multiply every 20 minutes. This helps the organis..
