What is Bakelite and example?

It is formed from the condensation reaction of phenol and formaldehyde. The initial product formed is a linear polymer called Novolac. On heating Novolac with HCHO, it undergoes cross-linkage to form an infusible solid called bakelite. Bakelite is an example of a thermosetting polymer.

What is the formula of Bakelite?

Bakelite molecular formula: (C16H26O2)n[7]

What is Bakelite and its structure?

Bakelite – Structure Preparation and Uses: Bakelite is an early plastic made from phenol and formaldehyde. It was created in 1907 by Leo Hendrik Baekeland, a Belgian-American chemist. Bakelite was the first synthetic plastic, and it was used for a variety of products including radios, telephones, and kitchenware.

What is the unit of Bakelite?

The monomer units of bakelite are phenol and formaldehyde.

What type of material is Bakelite?

Bakelite, trademark of phenol-formaldehyde resin, trademarked synthetic resin invented in 1907 by Belgian-born American chemist Leo Hendrik Baekeland.

What is Bakelite material?

Polyoxybenzylmethylenglycolanhydride, better known as Bakelite (/ˈbeɪkəlaɪt/ BAY-kə-lyte), is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde.

Is Bakelite A insulator?

The National Museum of American History houses the original Bakelizer, the steam pressure vessel used by chemist-entrepreneur Leo Hendrik Baekeland to commercialize his discovery of Bakelite – the world’s first completely synthetic plastic.

What is Bakelite reaction?

Bakelite is an insulator because it has very high resistance. It is a thermosetting polymer and has high strength. It is used for making electric goods such as switches.

What is the major use of Bakelite?

Bakelite is also called a co-polymer. Reaction: Phenol reacts with formaldehyde to produce o-Hydroxy methyl phenol. Now produced complex (o-Hydroxymethyl phenol) and phenol come together to form Bakelite. Hence the obtained product in the above reaction is Bakelite.

What’s the difference between Bakelite and plastic?

Solution : Bakelite is obtained by condensation reaction of phenol and formaldehyde. It is used in making electrical switches and switch boards. It is thermosetting polymer because on heating it undergoes extensive cross linking in the mould.

How was Bakelite invented?

Bakelite is different from other plastics due to its unique properties. The key difference between Bakelite and plastic is, Bakelite is the first synthetically produced thermosetting plastic with heat resistant and non-conductivity of electricity.

Why Bakelite is used in electrical appliances?

Made by combining phenol, a common disinfectant, with formaldehyde, Bakelite was originally conceived of as a synthetic substitute for the shellac used in electronic insulation. However, the strength and moldability of the substance, combined with the low cost of producing the material, made it ideal for manufacturing.

Is Bakelite biodegradable?

Bakelite is a thermosetting plastic. It is a poor conductor of heat and electricity. Hence, it is used for making electrical switches and plugs.

Is Bakelite a thermosetting plastic?

-Bakelite has phenol and formaldehyde as its monomers , the resulting polymer so formed does not contain a biodegradable functional group hence it is also non – biodegradable .

Is Bakelite heavy or light?

Bakelite is a thermosetting polymer which are cross linked or heavily branched molecules, which on heating undergo extensive cross-linking in moulds and again become infusible. This can not be reused means it can’t regain their original shape after melting.

What is modern Bakelite?

Bakelite feels heavier when compared to some other types of plastics, like celluloid. Hold another type of plastic you have identified in one hand, and a piece you know to be Bakelite of approximately the same size in the other. You will often notice the heavier feel of Bakelite.

Is Bakelite a natural polymer?

It is also called phenol-formaldehyde resin; the name comes as phenol and formaldehyde, which are the main compounds responsible for making bakelite resin. It is hard, incapable of fusing, has a good surface hardness, is dimensionally stable, and is chemically resistant.

What is the difference between Bakelite and polythene?

Cellulose is a natural polymer made up of glucose. Bakelite, PVC and neoprene are synthetic polymers.

What was the first polymer?

Bakelite is a thermosetting polymer i.e. they can be softened by heating only once i.e. once they are moulded and harden on cooling, they cannot be softened again. Whereas, polythene is a thermoplastic polymer i.e. softening and hardening can be repeated again and again.

What is Bakelite and melamine?

The first synthetic thermoset polymer (a phenol-formaldehyde (PF)), known as Bakelite, was obtained in 1907 by Baekeland through the polycondensation of phenol with formaldehyde. Bakelite was commercialized in 1909–1910 [3].

Who is father of plastics?

The Belgian-born chemist and entrepreneur Leo Baekeland invented Bakelite, the first fully synthetic plastic. Colorful objects made of Bakelite—jewelry, telephones, radios, and billiard balls, to name just a few—brightened everyday life in the first half of the 20th century.

What is the history of Bakelite?

Bakelite is the first thermosetting plastic made from synthetic components. It is a phenol formaldehyde resin. Melamine Resin which is also called melamine formaldehyde is one of the most common plastics used to make kitchen utensils and other household products. Melamine formaldehyde is a thermosetting plastic.

What are two types of polymer?

Bakelite was the major form of “art plastic” from the 1930s through to the 1950s. It was patented by Belgian born Leo Hendrik Baekeland in New York, in 1907, and was the first truly synthetic and thermosetting plastic. Thermosetting meant that it could not be melted or changed by heating once formed.

Is Bakelite a resistor?

There are two types of polymers: synthetic and natural. Synthetic polymers are derived from petroleum oil, and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted.

Is Bakelite a good conductor of heat and electricity?

Insulator- polythene, wood, bakelite, paper, thermocol, rubber. Was this answer helpful?
