Kevlar Rope

I have booty'd about 150m of 10mm static rope that I thought was plain old industrial grade kernmantle. Turns out its got a Kevlar core. Looks like its wound in exactly the same as a normal nylon static core.
My initial concerns about breaking strain and heat dissapation have subsided now I've done a bit of googling. Looks like its got a yield strength of around 15000pounds (about 6000kg) at which 1% stretch will be achieved. Appears its also fire retardant which would mean in theory that it should cope with being run through a descender.
Appears its also insanely expensive.
Can anyone shed any more light?

it sounds dangerous, you should give it all to me for testing.
I have a special test rig where you tie it to the cliff and jumar up and down on it with a lot of gear on, swearing. My current rope was given to me (retired from window cleaning) in 1996 for the FA of Red Edge, and the test is still progressing. But i think i can fit yours in.

Nice try :) More than happy to send you a few metres if you want to proof it to destruction.....

Good, I've used them for at least 5 days climbing this year in the Grose, the blue of the 2 is getting a bit fuzzy. led on the red as a single and took falls on it too.
