which polymer is used in making non-stick surface-coated Utensils?
- PHBV
- Nylon 6,6
- Teflon
- Buna-N
The Correct Option is C
Solution and Explanation
Teflon is used for making non-stick-coated utensils. The scientific name of Teflon is polytetrafluoroethylene (PTFE). It is a synthetic fluoropolymer that is made from the polymerization of tetrafluoroethylene (which is a monomer). It has a non-stick property along with high-temperature stability and chemical resistance. The non-stick property reduces the excess oil and thus promotes healthier cooking.

Polymers
Polymers are large molecules composed of repeating subunits called monomers. The process of joining monomers to form a polymer is called polymerization. Polymers can be made up of natural or synthetic materials and can have a range of physical and chemical properties.
There are two main types of polymers: addition polymers and condensation polymers. Addition polymers are formed by the addition of monomers that have unsaturated bonds, such as ethylene, which forms polyethylene. Condensation polymers are formed by the condensation of monomers that have two or more reactive groups, such as nylon, which is formed by the condensation of diamine and dicarboxylic acid.
Polymers have a wide range of applications due to their unique properties. They can be flexible or rigid, transparent or opaque, and can have different levels of strength and durability. Polymers are used in a variety of products, including plastics, textiles, coatings, adhesives, and composites.
Polymers have also had a significant impact on medicine. Synthetic polymers, such as polyethylene glycol, are used in drug delivery systems, while biocompatible polymers, such as poly(lactic acid) and poly(glycolic acid), are used in tissue engineering and drug delivery. Additionally, natural polymers such as proteins and polysaccharides play important roles in biological processes and are used in biotechnology applications.
The study of polymers, known as polymer science or macromolecular science, has led to the development of new materials and technologies that have revolutionized many industries.
