Uses of polymers Polymers are used in almost every area of modern living. Grocery bags, soda and water bottles, textile fibers, phones, computers, food packaging, auto parts, and toys all contain polymers. Even more-sophisticated technology uses polymers.
What is polymer and its uses?
Polymers, a large class of materials, consist of many small molecules named monomers that are linked together to form long chains and are used in a lot of products and goods that we use in daily life.
What are polymers most used for?
Organic polymers Polymer Abbreviation Uses Polyvinyl chloride PVC Pipe (mainly draining), fencing, lawn chairs, hand-bags, curtain clothes, non-food bottles, raincoats, toys, vinyl flooring, electrical installation insulations, etc. Polychlorotrifluoroethylene PCTFE valves, seals, gaskets etc.
How is polymer used in everyday life?
Polymers are used to make electronic components, paint, plastic bottles, sunglass lenses, DVDs and so much more! For instance, poly(vinyl chloride) is a strong, corrosion-resistant polymer commonly used in plumbing applications, whereas polyethylene is an example of a flexible polymer found in plastic bags.
What are 3 uses of polymers?
Uses of polymers new packaging materials. waterproof coatings for fabrics (eg for outdoor clothing) fillings for teeth. dressings for cuts. hydrogels (eg for soft contact lenses and disposable nappy liners) smart materials (eg shape memory polymers for shrink-wrap packaging).
What are 4 types of polymers?
Terms. Synthetic polymers are human-made polymers. From the utility point of view, they can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers.
What are the 3 main types of polymers?
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength.
What are the 2 types of polymer?
Polymers fall into two categories: thermosetting plastic or thermoset. thermoforming plastic or thermoplastic.
What are the most important polymers?
By far the most important industrial polymers (for example, virtually all the commodity plastics) are polymerized olefins. Olefins are hydrocarbons (compounds containing hydrogen [H] and carbon [C]) whose molecules contain a pair of carbon atoms linked together by a double bond.
What is polymer with example?
Polymer is a substance made up of a large number of smaller molecules that link together to form larger molecules. An example of a synthetic polymer is plastic. An example of a natural polymer is rubber.
Can we live without polymers?
Either way, both natural and synthetic polymers play a huge role in everyday life, and a life without polymers might actually not exist. Cells build our bodies, and cells are built of polymers. Plants are built of cellulose, which is a polymer. If polymers would suddenly disappear, life would disappear with it.
Which is an example of a biological polymer?
They are produced by polymerization, and occur either naturally or synthetically. Examples of natural polymers are cellulose, shellac and amber. Biopolymers such as proteins and nucleic acids play crucial roles in biological processes. A polymer produced by a living organism is called a biopolymer.
Why is polymer science important?
What are Bio-Polymers? Bio-polymers are the basis of all life on our planet. Polypeptides (proteins) and polynucleotides (DNA and RNA) dominate the functional and informational machinery of life, while polysaccharides (sugars) are important in physical structure, energy storage, and intermolecular interactions.
What are some common polymers you use in your life?
Polymers become the raw materials for products we now use every day, including: synthetic clothing, fiberglass, plastic bags, nylon bearing, polyethylene cups, epoxy glue, silicone heart valves, Teflon-coated cookware and our personal favorite, polymer based paints.
How do polymers work?
When monomers join with other monomers through the process of creating covalent bonds, they form larger molecules, called polymers. If it bonds with three or more molecules then three-dimensional, cross-linked structures can form [source: Innovate Us]. Polymers can occur naturally, or we can manufacture them.
What is the common name for polymers?
Addition Polymers Chemical Name Trade Name or Common Name polyethylene poly(tetrafluoroethylene) Teflon polypropylene Herculon polyisobutylene butyl rubber.
What are the characteristics of polymer?
Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.
What is an example of a lipid polymer?
Lipids: water-insoluble molecules that can be classified as fats, phospholipids, waxes, and steroids. Fatty acids form complex polymers such as triglycerides, phospholipids, and waxes. Steroids are not considered true lipid polymers because their molecules do not form a fatty acid chain.
Are there different types of polymers?
There are several types of polymers. Among the main ones are: natural, synthetic, addition, condensation and rearrangement.
Is an addition polymer?
An addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products. Addition polymers are formed by the addition of some simple monomer units repeatedly. Generally polymers are unsaturated compounds like alkenes, alkalines etc.
Is DNA a polymer?
And even our DNA is a polymer—it’s made of monomers called nucleotides. The first man-made polymers were actually modified versions of these natural polymers.
What is difference between plastic and polymer?
The key difference between polymers and plastics is that plastic is a specific type of polymer. Plastics are comprised of a long chain of polymers, where polymers are composed of smaller, uniform molecules. Polymers are basically enormous molecules made with a massive amount of smaller, identical molecules.
What is an example of a thermosetting polymer?
Common examples of thermoset plastics and polymers include epoxy, silicone, polyurethane and phenolic. Different thermosets provide different advantages when used as a production material. For example, epoxies are highly elastic, tough and resistant to many chemicals while phenolic is highly flame resistant.
Is a natural polymer?
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. Vulcanized rubber is a synthetic (man-made) polymer, while pectin is an example of a natural polymer.
