Question

From the options given, identify the correct match(es) between the polymer products with the most appropriate processing technique.

Polymer Product	Processing Technique
P	Fishing rods
Q	Soft drink bottles
R	Plastic sheets
S	Plastic trays

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

Hint:

Match product shape with process: long rods $\Rightarrow$ pultrusion, bottles $\Rightarrow$ blow moulding, sheets $\Rightarrow$ compression, trays $\Rightarrow$ thermoforming.

Answer 1

The Correct Option is A, D

Step 1: Fishing rods (P).
Fishing rods are long, continuous, fiber-reinforced composites. They are manufactured using pultrusion (continuous pulling of fibers through resin and die). $\Rightarrow P \to 3$.
Step 2: Soft drink bottles (Q).
PET bottles are made using blow moulding, where preforms are expanded with air pressure. $\Rightarrow Q \to 4$.
Step 3: Plastic sheets (R).
Plastic sheets are typically formed by compression moulding (pressing softened material into sheets). $\Rightarrow R \to 1$.
Step 4: Plastic trays (S).
Trays and disposable containers are made by thermoforming—heating sheets and shaping them. $\Rightarrow S \to 2$.

Step 5: Conclude.
Correct mapping: $P-3,\; Q-4,\; R-1,\; S-2$ which is option (A). Final Answer: \[ \boxed{\text{(A) P-3; Q-4; R-1; S-2}} \]
