PVA sponge rollers
These Zeta-charge PVA sponge rollers are for semiconductor and thin-film industry applications. Select particles can be removed by adjusting the Zeta potential (ZP) of the PVA sponge rollers and controlling the electronic charge on them to either attract or repel charged contaminated particles on the surfaces of substrates. ZP values range from +40.0 and -40.0 MV, with a distinct ZP curve that controls particle attraction by selectively adjusting the pH of the process cleaning solution. The rollers are available in rib and nub roller designs.
