Question

Match the following polymers to the most appropriate product

• A. P-2; Q-1; R-4; S-3
• B. P-2; Q-4; R-1; S-3
• C. P-3; Q-1; R-2; S-4
• D. P-3; Q-1; R-4; S-2

Hint:

Matching polymers to products depends on their properties, such as impact resistance, transparency, and thermal performance.

Answer 1

The Correct Option is D

- Expanded polystyrene (P) is commonly used for soundproofing and insulation, making it suitable for soundproof walls (Option 3).
- Polyether ether ketone (Q) is a high-performance plastic used in motor bearings due to its excellent mechanical properties and high-temperature resistance, making it appropriate for motor bearings (Option 1).
- Polycarbonate (R) is a durable and transparent material often used in safety glass applications, thus the match is with safety glass (Option 4).
- Poly(butylene terephthalate) (S) is commonly used for manufacturing TV cabinets because of its strength and impact resistance, so it corresponds to TV cabinet (Option 2).
Thus, the correct matching is:
\[ \boxed{\text{(D) P-3; Q-1; R-4; S-2}}. \]
