  • Pad for use in a critical environment
    Publication number: 20030200994
    Abstract: A cleaning/polishing pad has a first surface with raised, substantially nubs, having a length greater than a width, arranged adjacent each other forming laterally alternating rows of nubs and having troughs interspersed therebetween, a second surface opposite the first surface, and a thickness. The troughs, which may contain polishing/cleaning chemicals, are divided into first and second groups of substantially parallel troughs. The groups of troughs are arranged at an angle to one another forming a hatch pattern. The pad can be formed to make roller brushes, circular brushes or manual wipes. For the circular brushes the nubs are arranged adjacent each other forming laterally alternating concentric circles of nubs. Micropores are interspersed within the pad having a gradient of pores with smaller pores towards the first surface and larger pores towards the second. There are no sharp edges or corners in/on the pad.
