Introduction Natural polymers, often known as biopolymers, include substances that arise naturally throughout the lifespans of plants, animals, microorganisms, as well as fungi. A polymer is a large molecule made up of numerous repeating structured subunits of such molecules. Polymers have become the foundation of 4 sectors − fibres, plastics, elastomers, as well as resins. Polymerization has been the process by which polymers are formed from their monomers. Polymers are tough to categorize owing to their incredibly complicated structures, diverse behaviour, and a vast array of uses. As a result, we categorize polymers based on the following factors: Source ... Read More

Introduction High-density polyethylene would be a thermoplastic polymer. The monomer unit is ethylene. High-density polyethylene is also known as PEHD (Polyethylene High Density), polythene alkathene, and polythene. When a plastic substance has the Resin Identification Code (RIC-2) symbol, it is manufactured of HDPE. It is commonly abbreviated as RIC-2. Later, HDPE might have been recognized as an essential raw material within the manufacture of a wide range of products. It contributes to even more than 34 percent of the worldwide plastic industry. You've undoubtedly seen doctors wearing special disposable attire when treating a corona patient. You'll be amazed to hear ... Read More

Introduction Polytetrafluoroethylene commonly known as Teflon refers to a synthetic type of element made of “tetrafluoroethylene fluoropolymer”. It is mainly created by the “radical polymerisation” that is free of several molecules of tetrafluoroethylene. Polytetrafluoroethylene is called PTFE as the chemical term that has numerous benefits in the current situation to all types of industries. What is Teflon? Teflon refers to a name that has been widely used in the making of non-stick material, especially for the cookware set. This is mainly made with a particular chemical bond namely tetrafluoroethylene. It refers to a thermoplastic element of polymer and the chemical ... Read More

Introduction Typically, the copolymer is made up of repeating units of 2 different monomers. Block copolymers, alternative copolymers as well as graft copolymers are some types of these copolymers. Replicating units are placed arbitrarily in random copolymers; alternative copolymers have them in an ordered fashion; block copolymers have monomers placed at endpoints, and graft copolymers have the monomer chains located at various locations on host polymers. What are Copolymers? 2 or more distinct monomer subunits joined together to form a polymer chain make up a copolymer. Remember that one kind of polymer is a copolymer. A polymer is a big ...

Introduction Polymers are macromolecules composed of tiny particles known as monomers. Polymers comprise a vast range of substances that are quite important in our daily lives. These polymers can be categorised in a variety of ways, including structure, chemical or physical characteristics, and so on. Polymers are classified into 2 categories: natural polymers (NP) as well as synthetic polymers (SP). Natural polymers (NP) are polymer complexes that are present in nature. Synthetic polymers (SP) are artificially generated polymer complexes. This is the primary distinction between natural as well as synthetic polymers (SP). What is a Natural Polymer? They are found ...

Introduction In polymer chemistry, a significant quantity of important and practical polymeric substances are formed by conventional transformations of functional groups of polyfunctional reactants. In such a reaction, a smaller molecule is produced as a byproduct. This process generally involves the combination of two or more monomers with distinct structures. Nylon 6, 6 is a condensation polymer synthesized by Wallace Carothers in 1935. Nylon 6, 6 was the first laboratory synthesized condensation polymer. Nylon 6, 6 is formed by condensing monomeric units of hexamethylenediamine and adipic acid. Wallace Carothers also contributed to the invention of neoprene. Other than synthetic ... Read More

Introduction The manufacturing process of different types of lightweight and flexible items is improved from before after considering the application of polystyrene. Styrene is the most effective monomer of polystyrene. Another term associated with polystyrene is ethyl benzene. Phenyl ethane and vinyl benzene are two other components in which all integrated precursors are included. Definition: Polystyrene Polystyrene is an important stiff, transparent and hard resin and is produced by the polymerization of styrene. At room temperature, a thermostatic polymer is found in a solid form. At the time of heating the component at a high temperature, polystyrene started ... Read More

Introduction Polypropylene is generally produced through a reaction of chain-growth polymerization that involves propylene. The polymer can also be known as a type of polypropylene and sometimes it is represented with the abbreviation form of ‘PP’. This type of polymer is called thermoplastic polymer, and it guides to soften by heating and can be remoulded. Definition: Polypropylene Polypropylene is a particular form of polypropylene and it is used for different ranges of purposes. It is mainly made from monomer propylene through a particular process. This type of plastic refers to the thermoplastic that is crystalline in form and it ... Read More

Introduction Polymer compounds are one of the most significant compounds as they are vastly used for various purposes. Polyurethane is an organic polymer commonly used for coatings in products. Polyurethane is used to prepare high-quality paints that offer better durability than traditional pains. It does not melt or boil upon heating. These are thermosetting polymers. Polyurethanes are produced with the linkage of urethane molecules bonds. What is Polyurethane? Polyurethane, also known as PU or PUR is a type of organic polymer created by the linkage of many organic units via urethane molecules. Most of them do not melt by applying ... Read More

Introduction Polymers are generally composed due to the reaction of di or tri-isocyanate with one polyol. Additionally, Polyurethane is another synthetic resin-type varnish. Moreover, there are various applications of the polyurethane foam such as sponges uses for washrooms and kitchens in every household and applied widely in the manufacturing units. Information about Polyurethane Foam Both of the elements, isocyanates and polyols can be used to construct the polyurethanes, on average hold two or more two functional groups of each molecule. In 2002, PUFs has proposed to be employed as the passive samplers in chemistry. In the housing properties, the PUFs ... Read More
