Using these "pure white" materials is often a beginners mistake, already discussed a lot in these forums as not realistic. Indead, no common material have such a high albedo. But some have such as spectralon (a fluoropolymer). Look at the picture below, it will remind you those washed out white renders obtained when albedo is too high

It is quite commonly used in optics, especially for sensors. Hollow spheres made of this material allow light bounce a high number of time, and are sometimes referred as "integration spheres" as they can collect light from a full hemisphere into a sensor.

Re: White materials with 100% albedo
You eggheads are just soooo much fun
actually that is interesting - and I wonder if the exporter writers could have some sort of warning about not using pure black/white? for new users. Maybe just a bit of text ot tooltip saying the suggested boundaries?
