Nonwoven flap rollers employed in the PCB or other sectors can be bonded with a synthetic resin that strengthens the roller, improves its performance and adapts it to different application phases.

The nonwoven grits are highlighted with acronyms, as our selection below:

SVF which stands for 320 grit silicon carbide abrasive. SSF: which stands for 400 grit silicon carbide abrasive.

The abbreviation D11 corresponds to the roller hardness and it defines the flaps quantity employed to obtain the required density. Finer is the grit, higher is the flaps quantity required.
