New England Ropes main website is at New England Ropes.
The site presents a lot of technical information about their products.

They cover Polyester on a PDF: "Performance Tested Climbing Ropes"

Our Nylon Accessory Cords feature a kernmantle construction designed and engineered with the same attention to detail as our dynamic climbing ropes. Nylon accessory cord is a perfect multi-purpose line for stringing accessories, keeping personal items off the ground, tie-down ropes, or as a decorative accessory for packs or other gear. All nylon accessory cords meet the EN564 standard for kernmantle ropes, and the OD Green and Black product in 7mm, and 8mm also conform to MIL-A-A-50139B Type I, II, and III requirements for military use. Available in 6 diameters and 14 colors. Each diameter is available in complementary light and dark versions as well as black.

Our Polyester Accessory Cord offers the best of both worlds. Polyester resists water, has less stretch, has super vibrant colors, and has greater UV resistance. Polyester is also more durable than nylon and its lower stretch offers more abrasion resistance. The Polyester Accessory Cord carries UIAA 102 and EN 564 certification.

Our nylon Prusik Cord strikes the perfect balance between firm and supple. We engineered prusik cord so that the rope has enough give to grip the climbing rope but is not so mushy that the knot locks up. This results in a smooth, controlled movement over the climbing rope and makes untying the prusik knot easier. Prusik cord is available in 6mm to 9mm diameters, each available in two complementary light and dark patterns.

Of course the PDF has pretty pictures of these rope choices.

You should have looked for this, before posting this thread.
And I should have looked for this, before I butted in.

The New England Ropes PDF does not tell you that you can use Polyester cord for a prusik, or that you cannot. The product complies with UIAA 102 for accessory cord, but not UIAA 101 for climbing ropes.

On the other hand, they are very clear that their own "Prusik Cord" is perfect for you.

My own feeling about New England Ropes is that the company has been in the business of making quality, high-performance ropes for specific applications. I trust their ropes entirely, and I use them with confidence for the uses the rope was designed for.

In other words, I recommend that you tie your prusik with the same static cord that your friends use. Or maybe even buy NE's special prusik stuff -- it's gotta be good!

Don't be a pioneer with safety on the rocks. Use the same knots, the same ropes, the same gear as your friends use.

(Edit to add...)
My own main rope is NE Apex 10.2 STD-DRY Green/Yellow. I think it's the absolute best rope for climbing on Canadian Rockies limestone, especially trad.
I don't know the brand of my static 7-mm prusik/cordelette, but it works very well, too.
