Kevlar is very UV sensitive but essentially inert to water. Large deep
water anchoring jobs (think oil rigs) and technical/research instrument
towing is done with Kevlar lines.
A concern about Phillystran is the water gets inside and freezes,
damaging the cover, so do seal the ends.
Kevlar 49 is the fiber in Phillystran. Everything you might want to
know about K49 is at

Kevlar may be strong, but it is adversely affected by rain and UV.
Don't forget to seal the end caps.

Elements are rain, wind, fire, and earth. All that other stuff is just
made up. Even the ancients knew that.

Uh, ya but heat will burn/melt the plastic jacket off of the
Phillystran and then it is exposed to the elements. Why do we call
the environment the elements, anyway. What has Earth, Fire, Air,
Water, and maybe phlogiston got to do with it?

Real kevlar rope is fire resistant. I have side scan sonar cable
that a bernzomatic torch will not melt.
The only way I can cut it is with a sharp hacksaw blade.
