The wipe Bemcot™ M-3 II from Asahi KASEI is made of an outstanding cupro-cellulose spunbound non-woven fabric. It has a very good absorption capacity and a strong resistance to most cleanroom chemicals. It is free of adhesives and binders and is extremely lint-free. The Bemcot™ M-3 II is the perfect wipe for the CD or DVD industry.

Product recommendation based on cleanroom classes
Of course, cleanroom wipes used in ISO 5 can also be used in ISO 9, but in this case the economic efficiency and usefulness should be considered.
A 1 to 1 allocation of cleanroom wipes to an air cleanliness class according to ISO 14644-1 is not possible. Recommendations can only be made on the basis of special properties relevant from a cleanroom technical point of view, such as "abrasion resistance" or "particle emission". Users can find further information on this in VDI Guideline 2083 Part 9.2.
