What is 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 is the structure of Bakelite?
Structure of Bakelite Bakelite is a Polymer composed of monomers, phenol and formaldehyde. The phenol-formaldehyde resin is a Polymer thermosetting. We are surrounded by materials, many of which, in one way or another, have a Polymer associated with them.
What is the structure of monomer of Bakelite?
A) Bakelite is a polymer formed by the polymerization reaction of phenol and formaldehyde. Thus, the monomers of bakelite are phenol and formaldehyde. The structures of phenol and formaldehyde are as follows: B) Nylon-6,6 is a polymer formed by the polymerization reaction of hexamethylenediamine and adipic acid.
What are the properties and uses of Bakelite Class 8?
1. Bakelite is a good insulator used in non-conducting parts of radio and electric devices like switches, automobile distribution caps, insulation of wires, Sockets, etc. 2. It is used to make clocks, buttons, washing machines, toys, kitchenware, etc.
What is Bakelite describe its formation write down its properties and give two uses?
Uses of Bakelite It is a thermosetting polymer and Bakelite has high strength meaning it basically retains its form even after extensive molding. Phenolic resins are also extensively used as adhesives and binding agents. They are further used for protective purposes as well as in the coating industry.
Is Bakelite linear or branched?
Bakelite is a space-network polymer. Unlike linear and branched polymers (see demonstration 25.2), which are composed of long molecules that make them more or less crystalline, space-network polymers are highly and irregularly cross-linked throughout the structure.
Is Bakelite thermosetting or thermoplastic?
thermosetting plastic
Bakelite is an example of thermosetting plastic.
What is the linear form of Bakelite called as?
Novolac
The initial product is a linear polymer called Novolac which is used in paints. Novolac on heating with HCHO undergo cross- linkage to form an infusible solid called bakelite. Bakelite is an example of thermosetting plastic. Therefore, Option D is the correct answer.
What are thermosetting polymers write formation and chemical structure of Bakelite?
Bakelite is a polymer made up of the monomers phenol and formaldehyde. This phenol-formaldehyde resin is a thermosetting polymer. We cannot deny the presence of polymers in our lives. We are surrounded by objects, most of which, some way or the other have a polymer associated with them.
What is the polymer of Bakelite?
phenol-formaldehyde resin
What is Bakelite? Bakelite is a polymer made up of the monomers phenol and formaldehyde. This phenol-formaldehyde resin is a thermosetting polymer.
Is Bakelite is a linear polymer?
What type of polymer is Bakelite?
thermosetting polymer
Is Bakelite homopolymer or copolymer?
Hence, Bakelite is a type of condensation polymer. The correct answer is option C. Note: Bakelite is the commercial name for the phenol-formaldehyde resin. This is a type of thermosetting polymer.
Is Bakelite a branched polymer?
Since we can see that Bakelite has a cross linked 3D structure it cannot be a branched chain polymer.
