Nylon-66 compared to nylon-6 has __________________?
Correct answer: B. More abrasion resistant properties
- A. Lower melting point
- B. More abrasion resistant properties
- C. Higher hardness
- D. All A., B. and C.
Explanation
Nylon-66 generally offers better abrasion resistance than nylon-6, making it useful where wear resistance is important. Option A is false because nylon-66 has a higher, not lower, melting point, so “all” cannot be correct.
