SPONGE-TECH™ Foam Cleanroom Wipes are an ideal wipe of choice when a high degree of absorbency is required. They are tough, low in particle generation and are comprised of 1/8″ thick reticulated (open-celled) polyurethane foam. These unique features give SPONGE-TECH™ Foam Cleanroom Wipes a high degree of effectiveness during the process of wiping where liquids are absorbed and contamination is trapped within the open cells.
