Which means that it absorbs water... which is what we've been discussing... ???

 

Nylon or any other moisture absorbing material reaches equilibrium or steady state absorption, so the amount varies by time and active surface area. 1.5% could be maximum absorption for a particular size and/or time...so both values can be correct. 8.5% on a wt% basis is substantial amount of moisture. Although possible, I cannot see how this could be likely under normal operating conditions.

 

Yep, that is why I'd like to know the test conditions.

Lots of high humidity conditions in the southern US 80-90% for months at a time. OTOH, not many cars are submerged in water for 24hrs and only have to worry about suspension noise.

 

Either means both in this case.

 

Neither condition affect the equilibrium amount absorbed, just the rate...comparison of sample with similar material and geometry will have similar EQ absortpion capacities.
