Constructed of soft, 100% polypropylene fabric that is low in halogen levels and particulate matter. The bonding pattern eliminates loose surface fibers and when material is cut, it can rebond and seal its own edges against linting. Surface particulate matter is trapped when wiping because of this bonding pattern. Will not damage delicate surfaces. Size: 11.5”W x 12”L. Can absorb over five times its own weight in liquids. Double-wrapped in anti-static packaging that can be air blown and taken into Class 100 clean rooms. Acid-resistant.
