This looks like the tech cord from New England Rope, commonly refered to as New England Tech Cord. I've not seen it branded as "Maxim" before, Google turns it up as the 'climbing' page on the New England Rope site:

Maxim Climbing
click on accessory cord
click on Tech Cord; Technical Data Sheet

You can compare that to the sheet from the Safety & Rescue page. It's the same stuff. The key is the Technora Core.

I carry some 3mm (3100lbs) New England Tech Cord in my pack and it is very cool stuff. However, there are trade offs. It is somewhat stiff and you can't melt the ends due to the high melting point (this could be an advantage). Probably the best bet is to use waxed whipping twine.

You can find some ramblings about high tech cords in this CPF thread.

The 3mm is going to be thicker and much stiffer than paracord, and the 5mm even more so.

My understanding is that they can lose a lot of their strength depending on the knot.

* I haven't found a source for the 3mm in a long time.

(oh, also be careful. they also sell an 'accessory cord' which is not the same as their 'tech cord')
