Plastic abrasive sheet

[Raymond AscroftParticipant @raymondascroft71629]

 

Could someone identify an abrasive sheet I obtained about twenty years ago please. It is on a thin plastic film similar to acrylic is a pale blue colour and the abrasive is more of a polish grade than an abrasive a lot finer than 1200 wet & dry. I think it was made before diamond dust became widely used.

I don’t think this is the answer you are looking for but Crocus Paper was a very fine polishing grade abrasive but as expected on a paper backing rather than plastic but hey it was blue.

 

Cheers

Hi Martin

 

Thanks for that, I have the dark brown Crocus Paper on a cloth roll similar to emery cloth but the plastic sheet gives a better polished finish and the surface texture is different to Crocus Paper unfortunately I have only a small square of the plastic left

Again probably not the answer but 3M do a product they call Microfinishing Film Sheets. As far as I can see these product either come with a backing material for fitting to powered tools or in sheets. I have tried to copy their description from the 3M data sheets.

 

 

Cheers
