What are the characteristics of polymers?

          Polymers can be processed in various ways. The characteristics of polymers depend on the chemical bonding between the monomers and the process used to make them. However, polymers have some common attributes.

         Generally, all polymers have long chains consisting of hundreds of monomers. Most polymers show a high resistance to chemicals. Look at the cleaning materials used in your house. When it comes in contact with your skin or eyes, it can cause rashes or itching. But they are safely packed in plastic bottles and the packaging remains unaffected by its contents.

          They resist heat and that’s why, most of the handles of cook-wares are made of plastics. They are good electrical insulators as well. Remember Bakelite, which is used to insulate electric wires. All electric appliances, cords and wirings are covered with polymeric materials.

          Polymers are light in weight, but have significant strength and their inherent properties can be enhanced by using a range of additives. They do not generally melt; because of their structure, they change from crystalline to a semi-crystalline form when heated.
