Question

An example of thermosetting plastic is:

• A. Polyethylene
• B. All of these
• C. Bakelite
• D. P.V.C.

Hint:

Thermosetting plastics like Bakelite harden permanently after heating and cannot be remolded, unlike thermoplastics like PVC or polyethylene.

Answer 1

The Correct Option is C

Bakelite is a well-known example of a thermosetting plastic. Thermosetting plastics are polymers that undergo a chemical change when heated, causing them to harden irreversibly. Polyethylene and PVC (polyvinyl chloride) are thermoplastics, meaning they soften and become moldable when heated and can be remolded. Therefore, Bakelite is the correct answer.
