Material composition of Scotch Brite!

Material composition of Scotch Brite!

(OP)
Hello,

does anybody know the material composition of Scotch Brite which is used for surface finish for steels, cleaning,...?

We have encountered some unexplained dielectric failures of a Scotch Brite polished contact system in vacuum. An untreated system works perfectly. A rough idea would really facilitate a deeper look into the problem. However, it may have nothing to do with it....

Thanks

RE: Material composition of Scotch Brite!

It's hard to find a direct answer on the 3M site as to the composition of Scotch-Brite pads.

Scotch-Brite pads (at least the original product line, it now include sponges & SS wool) consist of a spun polypropylene fiber with about nine grit variations: none, various sizes of alumina grit, or various sizes of silicon carbide grit.
