Here we will be learning about the types and uses of polymers. Basically, in our previous chapters we have already dealt with topics like what is polymer, its structure and properties, classification of polymers and the process of polymerization.So, here we will be taking a dive further in understanding the the concept more deeply and look at some of the other important aspects of polymers.
A polymer is basically a large molecule or a macromolecule formed by joining many repeated subunits. They may be naturally found in plants and animals (known as natural polymers) or may be man-made (called the synthetic polymers). Different polymers have a number of unique physical and chemical properties due to which they find usage in everyday life. As such, in this article, we will list some of the important polymers and their uses in the industries and other fields.
Types of Polymers
- Polypropene, also known as polypropylene, is made up of monomer propene.
- Polystyrene is an aromatic polymer, naturally transparent, made up of monomer styrene.
- Polyvinyl chloride (PVC) is a plastic polymer made of monomer vinyl chloride.
- The urea-formaldehyde resin is a non-transparent plastic obtained by heating formaldehyde and urea.
- Glyptal is made up of monomers ethylene glycol and phthalic acid.
- Bakelite or polyoxybenzylmethylenglycolanhydride is a plastic which is made up of monomers phenol and aldehyde.
Uses of Polymers
Let us now look at some of the uses of polymers.
- Polypropene finds usage in a broad range of industries such as textiles, packaging, stationery, plastics, aircraft, construction, rope, toys, etc.
- Polystyrene is one of the most common plastic, actively used in the packaging industry. Bottles, toys, containers, trays, disposable glasses and plates, tv cabinets and lids are some of the daily-used products made up of polystyrene. It is also used as an insulator.
- The most important use of polyvinyl chloride is the manufacture of sewage pipes. It is also used as an insulator in the electric cables.
- Polyvinyl chloride is used in clothing and furniture and has recently become popular for the construction of doors and windows as well. It is also used in vinyl flooring.
- Urea-formaldehyde resins are used for making adhesives, molds, laminated sheets, unbreakable containers, etc.
- Glyptal is used for making paints, coatings, and lacquers.
- Bakelite is used for making electrical switches, kitchen products, toys, jewelry, firearms, insulators, computer discs, etc.
