I think the film you refer to may be Ilford SFX which is described as "near Infrared" but is really HP% with an extended red spectrum. Have a look on the Ilford website for further info.
I tested it for B&W mag (UK) a couple of years ago. It's not as good as the real IR films but worth a try if you can get it. As a matter of interest it's also used in the old speed trap cameras in the UK.
You're looking at Super XX from Kodak, discontinued in the early 90's I think. Check out www.michaelandpaula.com for more descriptions of the film. Any available would be outdated by now but probably usable.
Morten, the images you have linked to is from an old stash of SXX. SXX was discontinued 12 years (or so) ago.
These are shots taken with SFX by a good freind using a Red 25 and Hassy/80mm souped in Microdol X: Dead Link RemovedDead Link Removed Dead Link RemovedDead Link Removed
