Grinding tapes are composed of at least two layers, a harder polymeric backbone and a softer oligomeric or monomeric (UV) adhesion film. Although greater stiffness of the grinding tape supports its carrier function, the thickness and viscosity of the adhesive film also determines the capability to embed elevated structures (Fig. 3.5), which in turn will affect the thinning process performance ...

The basic job of a separator is to separate on-spec material from oversize. You do not want this oversize material entering the product stream; it needs to be recirculated through the grinding process. But you also do not want to recirculate on-spec material. That wastes energy and raises costs. Getting this balance is key to separator efficiency.
