If nylon is sensitive to moisture absorption, why can it still function well as a tow rope for water skiers?
 
  What will be an ideal response?

Question 2

Why is a polyimide film ideal in a very high-temperature electrical application, even one in which the film may be slowly degraded?
 
  What will be an ideal response?

Answer to Question 1

The absorption of cold water is very slow in nylon. Furthermore, tow ropes are usually not totally submerged for long periods of time and therefore do not have

high absorptions. Furthermore, nylon ropes are seldom pulled to their limit in this application so the small decrease in tensile strength is not critical.

Answer to Question 2

Polyimide film has a very high temperature capability. Then as it might degrade, rather than melt, it remains a solid that keeps the electrical conductors separated. The char that is formed may eventually conduct, but char formation is usually a slow process.
