Examples of polymers in everyday life
What are 5 examples of polymers?
Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
What are polymers give example?
polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids.
What is the most commonly used polymer?
Today, both High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE) remain among the most commonly-used plastics.
What are 3 examples of artificial polymers?
These are also known as man-made polymers. Some of the examples of synthetic polymers are polyethylene (PE), polystyrene (PS), polyamides (nylon), poly(vinyl chloride) (PVC), synthetic rubber, teflon, epoxy, and several others [10].
Is glass a polymer?
The majority of glass is formed of sand, and when we melt it down, we generally add sodium carbonate. This results in a more durable glass. This is the glass you see in jars and windows every day, and it’s also the glass used in composites. hence it is not a polymer.
Is water a polymer?
Liquid water is a dynamic polydisperse branched polymer | PNAS.
Is Glue a polymer?
The polymer in Elmer’s glue is called polyvinyl acetate. Like many other polymers, polyvinyl acetate is arranged in the glue like many strands of thread. These strands of polyvinyl acetate slide past each other as the glue flows. A chemical in Tide is able to connect the strands together, so they can’t slide as much.
What are common polymers?
The eight most common types of synthetic organic polymers, which are commonly found in households are:
- Low-density polyethylene (LDPE)
- High-density polyethylene (HDPE)
- Polypropylene (PP)
- Polyvinyl chloride (PVC)
- Polystyrene (PS)
- Nylon, nylon 6, nylon 6,6.
- Teflon (Polytetrafluoroethylene)
- Thermoplastic polyurethanes (TPU)
Is sugar a polymer?
Carbohydrates are one of the four basic macromolecules of life. They are a polymer made up of monomers called monosaccharides. These building blocks are simple sugars, e.g., glucose and fructose.
What is a polymer class 8?
A synthetic fibre is also a chain of small units joined together. Each small unit is actually a chemical substance. Many such small units combine to form a large single unit called a polymer.
What is polymer and types?
Commercial Uses of Polymers

What are polymers 12?
15.1 Polymers are high molecular mass substances consisting of large numbers of repeating structural units. They are also called as macromolecules. Some examples of polymers are polythene, bakelite, rubber, nylon 6, 6, etc. 15.2 (i) Hexamethylene diamine and adipic acid.
What is meant by the term polymer?
Definition of polymer
: a chemical compound or mixture of compounds formed by polymerization and consisting essentially of repeating structural units.
Is rubber a polymer?
Natural rubber is produced from plants and is classified as a polymer. A polymer is a chemical compound with large molecules made of many smaller molecules of the same kind.

Is DNA a polymer?
DNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue.
Is wood a polymer?
Wood itself contains polymers such as lignin, cellulose, and various hemicelluloses but has very different properties from the synthetic polymers with which it is most often combined. Wood is less expensive, stiffer, and stronger than these synthetic polymers, making it a useful filler or reinforcement.
Is foam a polymer?
At present, polymer foam is one of the most widely used polymer materials and plays a very important role in the polymer industry [1,2,3,4,5,6,7,8].
