What are the properties of Bakelite?

What are the properties of Bakelite?

Bakelite has a number of important properties. It can be molded very quickly, decreasing production time. Moldings are smooth, retain their shape and are resistant to heat, scratches, and destructive solvents. It is also resistant to electricity, and prized for its low conductivity.

What property makes Bakelite so hard?

Bakelite is the commercial name for phenol formaldehyde resin. It is usually brown/amber but can be made in a variety of bright colors. It is liquefiable and malleable when heated and becomes permanently hard and rigid on cooling. Hence, it is a thermosetting plastic.

What are properties of plastic?

Properties of Plastics

  • They are light in weight and is chemically stable.
  • Easily moulded into different shapes and sizes.
  • Good insulation and low thermal conductivity.
  • Good impact resistance and they do not rust.
  • Good transparency and wear resistance.
  • Poor dimensional stability and can be easily deformed.

What is the Bakelite material made of?

A hard, infusible, and chemically resistant plastic, Bakelite was based on a chemical combination of phenol and formaldehyde (phenol-formaldehyde resin), two compounds that were derived from coal tar and wood alcohol (methanol), respectively, at that time.

What is Bakelite polymer?

Bakelite is a polymer made up of the monomers phenol and formaldehyde. This phenol-formaldehyde resin is a thermosetting polymer. As such, Bakelite is one of the commercially manufactured polymers that we witness in our daily lives.

Is Bakelite A insulator?

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.

Is Bakelite an insulator?

What are the 8 properties of plastic?

Properties of plastics

  • Plastic is chemically unreactive:Plastics do not react with air and water.
  • Plastics are poor conductor of heat and electricity:They do not conduct heat or electricity,so they be used as insulators.
  • Plastics can be moulded into different shapes.
  • Plastics are quite cheaper and easily made.

What are some of the properties of polymers?

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 the difference between Bakelite and plastic?

Bakelite is the first synthetic plastic and is known as a “material of thousand uses” due to its versatile applications. The key difference between Bakelite and plastic is, Bakelite is the first synthetically produced thermosetting plastic with heat resistant and non-conductivity of electricity.

What is Bakelite give the preparation properties and uses of Bakelite?

It can be quickly molded. Very smooth molding can be obtained from this polymer. Bakelite moldings are heat-resistant and scratch-resistant. They are also resistant to several destructive solvents.

Why Bakelite is poor conductor of electricity?

Detailed Solution Bakelite is an early plastic which was made from synthetic components and was used in the telephone casings, radio, electrical insulators, jewelry, kitchenware and more for its heat resistant and electrical non-conductivity properties. It is a poor conductor of electricity.

What are the properties of Bakelite plastic?

Bakelite Plastic Properties. ■ Bakelite is the trade name for phenol formaldehyde resin. ■ Its chemical name is polyoxybenzyl methylene glycol anhydride. ■ It is a thermosetting plastic. A thermosetting plastic is a plastic that liquefies and is malleable when heated. Then it becomes permanently hard and rigid when cooled.

Is Bakelite a polymer or a condensation polymer?

So, we can, in general, say that Bakelite is a condensation polymer or a phenolic resin. Before we move on to the preparation of Bakelite, it is important to know how a polymer is prepared. Polymers are formed by combining ‘monomer’ or single units using a range of reaction mechanisms.

Is Bakelite resistant to electric current?

Owing to its low electrical conductivity, bakelite is resistant to electric current.

What is the dielectric constant of Bakelite?

The dielectric constant of Bakelite falls in the range of 4.4 to 5.4. Fillers are used to increase the strength and enhance the properties of the Bakelite so that it can be used for various applications. Asbestos, wood flour, cotton flock, cotton pulp, gypsum, mica etc., are a few reinforcing fillers that are added in molding resins like Bakelite.
