Scrubbing Roller


Excellent effect in particle removal The AION Brush Roller has protuberances with superfine pores of circa 150㎛ on their suface and with their suppleness and softness peculiar to PVA sponge, efficiently removes particles without dam-aging the scubbed surfaces. PVA SCL Brush Roller application They are widely received as scrubbing materials for precision electronic components. Also, AION meets highly sophisticated needs by a new product line including SCL grade which allow very small defree of elution.
