Title: manufacturing of abrasive sponges
Post by: student77 on May 21, 2012, 09:44:31 AM

HI ! Does anybody knows method of manufacturing abrasive sponges ?

I am interested in - how abrasive grains ( Aluminium oxide or Silicium carbide) and phenolic resin are applied on foam.

Thanks! :)

This is a polyurethane rather than a phenolic resin, but maybe it will help answer some of your questions:

If not, this has been a relatively active area for patenting. Google patent, the WIPO site, or freepatentsonline should give you a lot of things to look at.
