Find out the composition and uses of commonly used plastic such as PVC , PET , thermocol , bakelite and melamine
Answers
Answer:Nylon is a synthetic polymer prepared in labs and produced by industries for its commercial importance. It is commonly used in the textile and fabric industry. Nylon comes under the family of linear polyamides.
Nylon 6 and nylon 6,6 are 2 commonly used types of nylon. In fact, Nylon 6,6 (widely used as fibres) is made from adipic acid and hexamethylene diamine.They have a compact molecular structure exhibiting excellent abrasion resistance. The monomers are joined by hydrogen bonding. Nylon’s characteristics which make it such a valuable material can be attributed to its strength, lustre, elasticity and resistance to damage by oil and chemicals.

Nylon Fiber: Nylon Fibre is used in clothing/apparels in shirts, underwear, raincoats lingeries etc. Industrial uses of Nylon are the production of Conveyer and seat belts, nets and ropes, parachutes and tents.
Polytetrafluoroethylene
It is commonly known as PTFE is a synthetic fluoropolymer of tetrafluoroethylene. It is of high molecular weight and made up of mainly carbon and fluorine.The best-known brand name of PTFE-based formulas is Teflon which is extensively used in cook-wares such as non-stick pans.

Bakelite
Bakelite is one of the oldest polymers that was synthesized by man. It is a thermosetting polymer and has high strength and retains its shape after moulding. It is one of the first polymer/plastic created in a laboratory. The polymer is formed by condensation of formaldehyde with phenol. Its chemical formula is (C6H6O·CH2O)n.
Bakelite has a high resistance to heat and chemicals and also has a low electrical conductivity due to which it is most commonly used for making electrical switches Bakelite is also used to make the handles of a variety of utensils. It is one of the most important and extensively used polymers for making components and parts of various items. Other uses of this polymer are seen in pipe stems.
Polyvinyl Chloride (PVC)
When talking about polymers of commercial importance we must discuss PVC. It is one of the most widely used polymers in the world. PVC is used extensively across a broad range of applications (used in building, transport, packaging, electrical etc. products), and this can be attributed to its highly versatile nature.
PVC is a highly durable and long-lasting material. It is thermoplastic in nature.It is formed after polymerization of vinyl chloride monomer. It is a very durable and long-lasting material which can be used in a variety of applications, either rigid or flexible, white black or a range of colours in between.
