Series 304-1

Polyester-cellulose wipe

Back to our polyester-cellulose wipes

Series 304-1, a polyester-cellulose non-woven wipe, is versatile, both in microbiologically controlled areas and in purely particle controlled areas. Although it is made of a non-woven fabric, the wipe has a certain abrasion and tear resistance (even when wet).
The cloth material combines the different strengths of cellulose (➜ absorbency) and polyester fibre (➜ abrasion resistance) and is therefore also a happy medium in terms of costs. In direct comparison to the series 300 and the series 303, the series 304-1 has a slightly higher ionic load. The hydro-bonded non-woven fabric is free of adhesives and binders, which is also ultimately reflected in the low extractable residues. In addition, the wipe has good chemical resistance, especially for the most common cleaning and disinfection applications. The blue dyeing enables the user to check how far a possibly aggressive liquid has spread in the wipe.

Product recommen­dation based on cleanroom classes


123456789low dust


ABCDE

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 generation". Users can find further information on this in VDI Guideline 2083 Part 9.2.
