I agree Mr. Jan. Hard to consider talc as an abrasive. Maybe in this case, for deburring, a not abrasive abrasive is good! Now I'm more interested in the surface of the belt than the talc part. Talc on a belt almost seems irrelevant as far as abrasiveness goes. Maybe it's more of a lubricant in this application?
I was just about to post the following when I saw your post:
Yes! Talc is what is in talcum powder. The Tur-Grit site says, “A non-woven belt used for cleaning, finishing, blending and deburring applications. The firm, stretch-resistant backing is suited for high belt tensions. Abrasive mineral: Talc”
Odd talc is considered an abrasive, “Talc is known for being the softest mineral on earth.” The site also says talc can be in a variety of colors. I’m surprised 3M didn’t glom onto that and use it to describe abrasiveness.

Can someone here who has one take a close up picture of the surface?
