Polyethylene and polypropylene ropes are rapidly destroyed in sunlight.

Barry,

There is a type of rope known here as Silver Rope. I understand that
it is manufactured from UV stabilised polyethylene and claims
resistance to sunlight. It is also claimed to be resistance to most
acids and alkalis.

It is a very low cost rope, white in colour, and is widely used in
marine applications.

I have halyards and tails of this stuff that have been in the weather
for 10 years with no significant degradation (superficially or
observed when the strands are opened up).

Silver Rope is about half the price of Dacron rope (though only about
80% of the strength of Dacron). It takes knots well (as well as the
better synthetic fibre ropes, it has a slightly greasy feel), good
abrasion resistance and it is easy to splice.
