Answer:
Difference between polyvinyl chloride and Bakelite
PVC and bakelite are polymer materials. The key difference between PVC and bakelite is that PVC is a thermoplastic material, whereas bakelite is a thermosetting material. Moreover, PVC is made from polyvinyl chloride, while bakelite is made from phenol-formaldehyde resin.

PVC is a thermoplastic, whereas bakelite is a thermosetting substance.
Explanation:
- Polyvinyl chloride (PVC) is a polymer made up of polyvinyl chloride. It's a chloroethene monomer-based thermoplastic polymer. PVC is a widely used polymer.
- The rigid and flexible forms of PVC are divided into two categories. The stiff PVC material is utilised for construction, whereas the flexible PVC is used for wiring and cables.
- When it comes to bakelite manufacturing, it's a multistep process that starts with the heating of phenol and formaldehyde in the presence of a catalyst. As a catalyst, HCl, zinc chloride, or ammonia base are commonly utilised.
- Bakelite A is the liquid condensation result of this process. Alcohol, acetone, and phenol are all soluble in it. Further heating causes this liquid to become partially soluble before hardening into an insoluble hard gum.
