Question

Match the Product with the most appropriate Processing Technique employed.

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

Hint:

Blow molding is commonly used for hollow items like bottles and boots, while thermoforming is used for creating products like cups. Calendering is used for films, and rotational molding is used for large, hollow objects.

Answer 1

The Correct Option is B

In this matching question, we are asked to match the products with the processing techniques employed in their manufacturing. Let’s analyze each option:
- Rainboots (P) are typically produced using blow molding (1), a process where a heated polymer is inflated into a mold to form hollow shapes like boots.
- Disposable plastic cups (Q) are generally manufactured using thermoforming (4), where a heated plastic sheet is molded into the desired shape.
- Soft drink bottles (R) are typically made using blow molding (1), which forms hollow plastic items like bottles.
- Flexible films (S) are commonly produced using calendering (2), where the polymer is passed through rollers to create thin, flexible sheets.
Thus, the correct matching is (B) P-1; Q-4; R-1; S-2.
