Nylon-6 as compared to nylon-66 is
A. Harder
B. More abrasion resistant
C. Having higher melting point
D. None of these
Answer: Option D
Solution(By Examveda Team)
Option A:HarderThis option is incorrect. Nylon-66 is harder than Nylon-6, not the other way around. Nylon-6 is known for its relatively softer characteristics.
Option B:
More abrasion resistantThis option is partially correct. Nylon-66 is indeed more abrasion-resistant than Nylon-6. Nylon-66 has better wear resistance due to its higher melting point and crystalline structure.
Option C:
Having a higher melting pointThis option is correct. Nylon-66 has a higher melting point compared to Nylon-6. The higher melting point contributes to its increased hardness and better performance in high-temperature environments.
Option D:
None of theseThis option is incorrect. As explained, Nylon-66 does have specific advantages over Nylon-6, including a higher melting point and greater abrasion resistance.
So, the correct answer is Option C: Having a higher melting point, as Nylon-66 does have a higher melting point compared to Nylon-6.
