Updated On: Feb 18, 2026
- Bakelite
- Polythene
- Terylene
- Neoprene
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understand thermoplastic polymers.
Thermoplastic polymers soften on heating and harden on cooling. This process is reversible and they can be reshaped repeatedly.
Step 2: Analyze the given options.
Bakelite is a thermosetting polymer and does not soften on heating.
Terylene is a polyester and is not classified as a simple thermoplastic in this context.
Neoprene is an elastomer.
Polythene softens on heating and can be remoulded, hence it is a thermoplastic polymer.
Step 3: Conclusion.
Therefore, polythene belongs to the class of thermoplastic polymers.
Thermoplastic polymers soften on heating and harden on cooling. This process is reversible and they can be reshaped repeatedly.
