Which of the following polymer is thermosetting polymer?

Why Bakelite is a Thermosetting Polymer?

• It becomes harder through the curing of a resin, prepolymer, or viscous liquid.
• The process of curing is accelerated by high pressure, mixing with a catalyst, or the application of the right amount of heat or radiation.
• A thermoset cannot be melted for reshaping once it has hardened.
• A thermosetting polymer includes things like polyurethanes, polyurea, bakelite, urea-formaldehyde, etc.

Terylene

• A synthetic polyester fibre is terylene. It is mostly utilised in fabric bags and designer materials.
• It is also referred to as “Dacron.”
• It is created by polymerizing terephthalic acid and ethylene glycol.

Polystyrene

• This synthetic aromatic hydrocarbon polymer is created from the styrene monomer.
• It can be applied to a variety of industries, including refrigeration and food packing.
• Polystyrene comes in the form of thermocol.
• Solid or foamed polystyrene are both possible.

Bakelite

• It results from the condensation of phenol and formaldehyde.
• It is utilised in a variety of products, including electrical insulators, radio and telephone casings, jewellery, kitchenware, pipe stems, children’s toys, and guns.

Neoprene

• It also goes by the name polychloroprene.
• It belongs to a family of synthetic rubbers made by polymerizing chloroprene.
• It is commonly employed in the production of goods like medical and sporting supports.
• Neoprene maintains its elasticity over a broad temperature range and demonstrates strong chemical stability.

Summary:

Which of the following polymer is a thermosetting polymer? (a) Terylene (b) Polystyrene (c) Bakelite (d) Neoprene

Bakelite is a thermosetting polymer. It can be irrevocably hardened into the required shape. The polymer that is obtained by irreversibly hardening viscous liquid prepolymer or a soft solid is called thermosetting polymer.
